Gateway/Firewall

The WAN ports are plugged into a switch so they can communicate over a Layer 2 network so there is no need to route between subnets
Each system operates in Gateway/Firewall mode in order to NAT each systems LAN to each WAN interface
The NAT option allows each system to provide DHCP on each phone subnet to simplify configuration
Each system listens on both interfaces for VoIP traffic using the built in SBC (Session Border Controller)
The network and dial plans must be built in order to route VoIP traffic between system extensions
Each system has a unique Site Prefix in order steer VoIP traffic to each fully qualified host name
Incoming calls will have the Site Prefix added to CLID on ingress to make a callback easier





Console – nmtui


If there is no DHCP server on the network the server will not get an IP address.
Using the command ‘nmtui’ omitting any quotes an IP address can be set statically and then used to login to the GUI.





Use the tab key on the keyboard to select Edit a connection




Use the tab key on the keyboard to select the desired interface and press Enter




Use the tab key and keyboard arrows on the keyboard to select elements.
The Default is Automatic (DHCP)
To edit this connection Tab to <Automatic> and press Enter
Tab to Manual and press Enter






Keep using the keyboard to enter any static configurations, then tab or use arrows to select OK and press Enter
After pressing Enter use the <Back> button to exit nmtui





Console – service network restart


From the root prompt type ‘service network restart’ omitting any quotes to restart the network with the new static IP address.





GUI|Login


Using the IP address of the server and the default management port :5555 login to the server using an Internet Browser
Example:

The default admin username is 'admin'
The default admin password is 'admin'
On your first login you will be required to change the default admin password.





Server Module – Configuration Wizard


Since each system is a new install after the first admin login you will be prompted to run the ScopServ Initial Server Configuration Wizard.
Before proceeding make sure you have your server’s serial number handy so you can activate all of the menus and proceed with the configuration wizard.
If you have the serial number proceed with the wizard by pressing Next.



Server Module – EULA

By clicking on Next on the EULA page you are agreeing to the terms of the ScopServ End User License Agreement.



Server Module – Listen Port


The default GUI listening port is 5555.
Proxy information can be entered if the required Internet connection uses a proxy.
To send voicemail or fax to email using a third party email server tick the ‘Smart Relay’ check box and fill in the credentials needed to connect to the external email server.
Click Next to proceed.



Server Module – Registration Details


Enter the Serial Number purchased from ScopServ and system details.
Click Next.




Server Module – Admin Password Change


In the field it is recommended to change the default admin password.
Since this is a lab environment leave the default password and click Next.


Server Module – NTP Server

Enter the IP or FQDN address of the NTP server.
Click Next.


Server Module – Network Configuration


Set the Fully Qualified Domain Name (FQDN) for the local system from the System Networking Lab – Table 1.
Set the network configuration as static for the local system using the information from the System Networking Lab – Table 1.
Set the DNS server information for the local system using the information from the System Networking Lab – Table 1.
NOTE:  The system is a fully capable DNS server and can resolve DNS for the network but a third party DNS server can also be used.
Press Next.



Server Module – High Availability


Skip any required High Availability Settings.
Press Next.



Server Module – Firewall Type


You will set the Firewall configuration later.
Choose No Firewall.
Click Next.




Server Module – Locale


Choose the language type that best suits your country profile to set the local tones and cadences configuration that best suits your local telco.
The Server is behind NAT option is configured if the server is behind a third party NAT router.  This setting manipulates SIP traffic to work behind the NAT router using the internal Session Border Controller (SBC)
For each local system use the Hostname using the information from the System Networking Lab – Table 1
NOTE:  If the server is behind NAT then ensure that any external firewall port forwards the TCP/UDP ports to the static IP address of the server.
Port examples:
5060-5061/tcp SIP signaling
10000-20000/udp SIP RTP traffic
4569/udp IAX2 signaling and RTP traffic
22/tcp SSH management
5555/tcp ScopTEL GUI
123/udp NTP





Server Module – Apply Changes and Reboot


Review changes and tick on Apply Changes.
Click Finish.

Network Configuration – Network Interfaces


On a new installation it may be necessary to add an eth1 interface in order to configure the WAN interface.
From the Configuration>Network>Interfaces tree check to see if both eth0 and eth1 interfaces already exist.
If the eth1 interface is already configured then from the Configuration>Network>Interfaces tree click on edit eth1.
If the eth1 interface is not configured, then from the Configuration>Network>Interfaces tree click on Add a  new Interface.



Network Configuration – WAN Interface


In this example the eth1 configuration from the lab exercise system is 1000.scopserv.local and the eth1 WAN interface is 192.168.100.1/24.
Substitute the IP address and subnet mask and MAC address for the system you are working on using the information table on page 1.
When finished click Add or Save depending on whether you must add eth1 or it is already configured.



Network Configuration – LAN Interface


In this example the eth0 configuration from the lab exercise system is 1000.scopserv.local and the eth0 LAN interface is 172.16.1.1/16.
Edit the eth0 interface and substitute the IP address and subnet mask and MAC address for the system you are working on using the information table.
When finished click on Save.



Network Configuration – Hostname


In this example the hostname configuration from the lab exercise system is 1000.scopserv.local and you will use the eth0 LAN address as the DNS server address which is also the DNS Server information from page 1.
Edit the default Hostname and when finished click on Save.




Network Configuration – Firewall Wizard


Click on each box listed to allow inbound traffic for each required service and click Next.




There is no need to deny any Outbound
Services in the lab so click on Next.



On the last step make sure to click on the the Apply Changes? [x] box and then click Finish to save the configuration.




Network Configuration – DNS Configuration Wizard


From the DNS tree click on Configuration


From the drop down list select the Wizard. Local Domain scopserv.local.

Click Close.



Network Configuration – DNS A Records - Table 2


Each server has a unique Fully Qualified Host Name (FQDN) on the network.
Each server will communicate with the others by using DNS A records.
A DNS record for each other system needs to be entered into the default zone for each server on the network.
Use this table to enter each A record for other systems on this network.
Notice that each A record will resolve to the WAN address of each server.  This is because each LAN address is behind NAT and will not be accessible by other servers.

Click on Zones.


Edit the scopserv.local zone.


Choose Record Type IPv4 Address (A).
Enter the Host name.
Enter the IPv4 address.
Make sure to use the data from the DNS A Records Table for each system.




Network Configuration – DNS A Record Configuration


NOTE that the default A record for the local system is already created by the DNS Configuration Wizard and uses the LAN address of the server.
Make sure each other A record is configured before proceeding to the next module.



Network Configuration – DHCP Subnet – Table 3


Use this table to create the DHCP server configuration for each system on the network.
Note that each scope belongs to a class B subnet so it can service more than 254 IP addresses.  In real scenarios a larger subnet might be necessary to provide DHCP to thousands of IP phones.
The Default Gateway belongs to the LAN address of each server so the DHCP client will NAT outbound to reach subnets that are not local.
Primary DNS is the local server which is configured with A records for each other server.
The TFTP server for each subnet is the LAN address of the local server which will use the Automatic Provisioning System to manage the configuration files for each IP Phone.
The NTP server for each subnet is the LAN address of the local server and the local server will act as a Network Time Protocol (NTP) server on each local subnet.




Edit the default DHCP Server configuration.

Telephony Configuration – Pre-Requisites


Objects like telephony extensions, Class of Service, and Outgoing Lines require that other objects exist before they can be properly and efficiently configured. Configuring these objects in the correct sequence will make first time installation much more efficient and promote a better understanding of each object’s intended function. It is best practice not to use Upper Case characters or Special characters when entering object names.
Here is a basic checklist to perform when setting up a new server for the first time: 
Edit Telephony Modules
Edit Feature Codes
Commit
Edit Services Startup
Interfaces Card Detect (optional but at least one physical interface must exist in order to provide a DAHDI timing source for Asterisk)
Create Interfaces
Create Incoming lines
Create Outgoing Line(s)
Verify Class of Service objects
Security Settings
Create Extensions
Commit and Services Restart


Telephony Configuration – Edit Telephony Modules


It is essential that pre-requisite modules be enabled prior to anything being configured on the server. This is to ensure that only required VoIP protocols and PSTN hardware modules are loaded during startup.
Edit and save the values for tab Configuration>Telephony>Configuration>Telephony Modules.
After saving Commit all changes

Recommended values are:
Include all default values
Analog Interfaces (DAHDIl)
Digital Interfaces (DAHDI)
SIP Channels
IAX Channels
Virtual Fax
Emergency Lines
Queues and Agents
Conferences
IVR Report/Logging
Scheduler
Asterisk Manager
Jabber (XMPP) Channels

Telephony Module – Dynamic Host Mode VoIP Accounts


Create a dynamic SIP Friend for each server referencing SIP VoIP Interfaces – Table 4-9.
In this example you are configuring server 1000.scopserv.local with a Dynamic entry of 802to801 so the remote server 2000.scopserv.local can register to 1000.scopserv.local.
You will have to create a dynamic entry for all other systems on the network to allow registrations to this local server.
Type is SIP.
Trunk Type is Friend to allow calls in both directions.
Enter the remote Hostname into the Name field.
When done click on the Server tab.




This example shows the Server tab requirements for Host Mode Dynamic
Host Mode Dynamic sets the SIP registration credentials for other systems with VoIP accounts set to Host Mode specific to allow the remote system to register to this account. 
Since we are not allowing only incoming registrations 
. from a specific Host/IP the Default Host/IP can be left blank.
The default Port is 5060 and can be left blank.
The Enable Proxy Settings checkbox must be checked and the From User Default info will appear in the CLID of incoming calls.
The From User must be left at the Default setting
Click Add when done.




Telephony Module – Specific Host Mode VoIP Accounts
Create a specific SIP Friend for each server referencing SIP VoIP Interfaces – Table 4-9.
This example shows the General tab requirements for Host Mode specific.
Host Mode specific sets the SIP registration credentials to register to Host Mode Dynamic VoIP accounts on other servers in the network.
Since we must register the local system 1000.scopserv.local to 2000.scopserv.local will use an account name of 801to802.
Type is SIP.
Trunk Type is Friend to allow calls in both directions.
When done click on the Server tab.




This example shows the Server tab requirements for Host Mode Specific.
Host Mode Specific sets the SIP registration credentials to register to Host Mode Dynamic VoIP accounts on other servers in the network.
Since we must register 1000.scopserv.local to other servers a Specific VoIP account must be created for this local server
Enter the remote Hostname into the Host/IP field to route SIP registrations to the remote server
Register as User Agent must be checked

Telephony Module – Outgoing Lines Dial Plan Summary


An Outgoing Line for each remote server must be built for each local server based on the Outgoing Line Dial Plan – Table 17-22.
The Outgoing Line Custom Dial Plan determines which VoIP Interface to use by recognizing digits dialed to steer the call to the desired server.
For example when the digits dialed from system 1000.scopserv.local are 8022001 the server recognizes 802 as the prefix for the 801to802 VoIP Interface and passes 2001 to server 2000.scopserv.local.  2000.scopserv.local then matches the incoming digits 2001 to local extension 2001 causing the phone to ring.
The same rules remain true for any VoIP (SIP, IAX2, Skinny) or TDM (ISDN PRI) trunk that supports DNIS routing.
Here is the configured Outgoing Lines summary for 1000.scopserv.local.





Telephony Module – Outgoing Lines Dial Plan Configuration


Click Add a New Outgoing Line.
Give the Outgoing Line an alphanumeric name (no upper case or special characters).
Select the correct outgoing Trunk that matches the dial plan.
When done Click on the Dial String tab.


Choose Type Custom Dial String from the drop down list.
Since Dial Plans rely on X the Dial String includes the site prefix and the wild card upper case XXXX.
Number of digit to strip 3 strips the first 3 digits from the outgoing call sending only the last 4 digits allowing the remote server to do a dial plan lookup and steer the call to a matching extension using the Incoming Lines Dial Plan.
When done click on the Dial Options tab and use the Outgoing Line Dial Plan – Table 17-22.  Note that the Dial Options are common for each server.
When done Click Add.




Telephony Module - Manager > Class of Service default


Newly installed 2.5 systems include all Outgoing Lines in the default Class of Service for all tenants.
You should check the Class of Service to make sure each newly created Outgoing Line is allowed for the Class of Service assigned to each extension.
Add a new Class if you need to create a custom Class of Service.



Telephony Module – Security


SIP Phones are SIP User Agents.
For security, SIP User Agents must register to the SIP Registrar via username and password authentication.
It is typical for the SIP protocol ports to be open or forwarded to the ScopTEL server if a third party Firewall is implemented.
When the SIP ports are exposed on the Firewall it is common for hackers to attempt brute force attacks on the server. Such attacks systematically request authentication using common dial plan Extensions and trivial passwords.
Examples of such brute force attacks:
Extension range 1000-3000
Systematic Password attempts using passwords 1000-3000
Systematic Password attempts using passwords 0000, 1234, 1111, 4321, 123456, 7654321
Therefore if a secure password policy is used it will prevent the overall majority of hackers from registering a SIP Extension or SIP Trunk with the server for fraudulent purposes.
Examples of secure SIP password policy
Minimum password length of 8 alpha numeric characters.
No Dictionary words
Minimum 2 Upper Case characters used
Minimum 2 numerals used
Passwords should be unique for each extension
The same policy enforcement should be in effect when configuring Voicemail Passwords except Voicemail Passwords cannot contain Alpha characters and must be numeric.
A poorly implemented Voicemail Password Policy can allow a hacker access to thru dial capabilities from a mailbox configured to allow outdial capabilities.
Therefore Voicemail Passwords must be strict regardless of inconvenience caused to end users.
Voicemail Password should never match the extension number. Example: Extension 100, Voicemail Password 100
Voicemail Password should never be trivial.
Examples: 0000, 1234, 1111, 4321, 123456, 7654321



To set a Global Password Security Policy navigate to Configuration>Telephony>Configuration>Security.
The SIP and IAX2 Password Policy is set independently of the Global Voicemail Password Policy.
If the Options to automatically fix invalid password?[x] is checked then non-compliant passwords will be made compliant after a commit (recommended).




Telephony Module – Extensions


Typical Extensions types are:
SIP Extension (IP Extension using the SIP protocol)
IAX2 Extension (IP Extension using the IAX2 protocol)
Zap Extension (analog FXS extension using Sangoma or Digium cards. Sangoma and Digium cards should not coexist in the same server)
Voicemail Extension (Voicemail box only)
HotDesk Extension
A HotDesk Extension is an Extension that logs into a physical Extension using the HotDesk Feture Code, HotDesk Extension number and required password.
By logging into a physical Extension the HotDesk Extension can make and receive calls from any extension which allows the HotDesk Feature Code in its assigned Class of Service. Caller ID incoming and outgoing will be automatically manipulated to display HotDesk user information.
Virtual Extension
A Virtual Extension is a very advanced Extension type which allows a user to login to the ScopTel GUI and use the Realtime Monitor and customize Call Detail Reports and other types of reports.
Advanced options can be configured to ring multiple destinations and automatically forward copies of voicemail messages to multiple extensions
User Options for Virtual Extensions include Follow Me, Camp-On, Personal IVR destinations
Custom Forwarding Rules can be defined for:
Call Forward Immediate • Call Forward Busy
Call Forward No Answer
Call Forward Unavailable (forward when physical extension is offline)
It is possible to Immediate Forward a Virtual Extension to make an Application available within an IVR context for inbound PSTN callers.

Ring Group Extension
A Ring Group Extension automatically Immediately Forward it’s calls to configured Follow Me destinations
Advanced options can be configured to ring multiple destinations and automatically forward copies of voicemail messages to multiple extensions
User Options for Virtual Extensions include Follow Me, Camp-On, Personal IVR destinations
Custom Forwarding Rules can be defined for:
Call Forward Immediate
Call Forward Busy
Call Forward No Answer
Call Forward Unavailable (forward when physical extension is offline)
It is possible to Immediate Forward a Virtual Extension to make an Application available within an IVR context for inbound PSTN callers.
Shared Extension
A Shared Extension can be configured so that multiple extensions can ring when the pilot DN is dialed but depending on the busy status of the extension(s) one or more extensions can ring but the busy extension will not ring
