Module 5 - ScopTEL IP PBX Software - Interface Groups and Outgoing Lines
Interfaces Card Detect
If any analog FXO/FXS or T1/E1 or BRI cards are installed then you
must do a “Card Detect” to recognize and configure that hardware before
the drivers and configurations can be properly loaded. Configuration
> Telephony > Interfaces > Detect Cards
Follow the pop-up windows to complete the card detection
procedure and be certain to read and follow any instructions that will
appear in those pop-up windows. After your PSTN hardware is detected and
the required services are running it will be necessary to configure
regional properties and gain settings for each of your PSTN cards and
ports. If a change is made to any settings on the “Interfaces” tabs it
is a good practice to “Commit” those changes and then restart the
following services in the correct order. First navigate to the “General”
tab…
The correct order to reset services is:
Stop the “Telephony Server”Restart the “Analog/Digital Modules (Zaptel/Wanpipe)
Start the “Telephony Server”
Interface Groups
Once your PSTN hardware is detected and the required services are running you can set up Interface Groups.
An Interface Group is a “pool” of physical DAHDI interfaces:
If you are using DADHI hardware
Navigate to Configuration>Telephony>Configuration>Interfaces>Interface Group>Add a new Group
The Group Interface can be a collection of DAHDI PRI, FXO, interfaces but it is normally a collection of only one technology.
The purpose of an Outgoing Line Group is to isolate outgoing
physical interfaces to specific Applications, Extensions, Outgoing
Lines, Emergency Lines, Special Lines.
For example there are 10 FXO (analog PSTN lines aka POTS lines) ports shared between two companies:
FXO ports 1-2 belong to Company ABC
FXO ports 3-4 belong to Company XYZ
Group 1 is a collection of FXO ports 1-2
Group 2 is a collection of FXO ports 3-4
Therefore Group 1 belongs to Company ABC and Group 2 belongs to company XYZ.
In this screenshot a PRI Outbound Group is configured using T1 B
channels 1-23 in Descending order 23>1 to prevent network glare.
Outgoing Lines | General
Outgoing Lines use dial patterns to select from ScopTEL Interfaces
to place outgoing calls. Recommended interfaces are DAHDI, SIP. Other
interface types exist like MGCP, IAX2, SCCP/Skinny, H323 are available
but fall into extended or limited support categories. Outgoing calls can
be PSTN interfaces or Private TIE trunks. A lot of detailed
configuration information can be found on the ScopTEL knowledgebase at https://service.scopserv.com/
To create an Outgoing Line navigate to Configuration >
Telephony > Lines > Outgoing Line then Click “Add a New Outgoing
Line”. Enter a unique name for the new Outgoing Line. The name can match
the dial pattern used for easier documentation of the configuration.
Outgoing Lines | NPA-NXX
One of the most powerful and unique features in the ScopTEL IP
PBX is the ability to download the entire NPA-NXX dial plan for any
supported Area Code and Prefix. This greatly simplifies the LCR
(Least CoSt Routing) dial plan configuration for the server. Hours and
possibly days of configuration are reduced to seconds. However in this
tutorial only a simple “Custom Dial String” option will be used.
After clicking on the “Dial String” tab choose “Custom Dial String” and the page will automatically refresh.Outgoing Lines | Custom Dial Plan Strings
Custom Dial Plan Strings
X matches any digit from 0-9
Z matches any digit form 1-9
N matches any digit from 2-9
[1237-9] matches any digit or letter in the brackets (in this example, 1,2,3,7,8,9)
. wildcard, matches one or more characters
! wildcard, matches zero or more characters immediately
Examples
NXXXXXX matches a normal 7 digit telephone number
1NXXNXXXXXX matches an area code and phone number preceded by a one
9011. matches any string of at least five characters that starts with 9011, but it does not match the four-character string 9011 itself.
# matches a single # key press
Outgoing Lines | Dial String
Type= drop list of possible pre configured or Custom Dial Plan rules
Dial String= A matching pattern of digits a user can dial from their extension
Access Code (Prefix)= Optional Outgoing Dial Plan Prefix. This
digit is always stripped and never passed to the physical interface.
This is most often used by PBX PSTN prefixes like 9 that must be
stripped before processing by the PSTN carrier.
Number of digit to strip = Number of prefixed leading digits stripped from the “Dial String”
Prefix to add to Number = The digit(s) prefixed to the outgoing call after digits are dialed
Authentication (PIN) can be used to force user authentication before call is placed.
Once all fields are completed click on the “Dial Options” tab.Outgoing Lines | Dial Options
Dial Options must be configured if you wish to provide additional
features such as call recording, early media with progress, and T.38
Gateway options
It is often useful to have a unique Music On Hold source for each Outgoing Line if the user places an outgoing call on hold.
Once these fields are configured click on the Caller ID tab.Outgoing Lines |Caller ID
On physical interfaces that support custom ANI to be set on
outgoing calls it is useful to define a global Name and Number for
outgoing calls. Fill in the custom name and number for
outgoing calls here if the Outgoing Line > Trunk supports custom ANI
Note that FXO interfaces do not support custom ANI but in this
example the custom “CallerID Number” and “Caller Name” are configured.
Advanced CallerID options can be selected to comply with https://tools.ietf.org/html/rfc3325
If you enable ‘Use original Inbound CallerID’ then the CallerID
received on the Incoming Line will be used as the Outgoing CallerID for
any forwarded calls. This applies to any extension forwarding a call
by Extension|User Options or Feature Code or Incoming Line|Destination
making use of the Outgoing Line by the matching Class of Service.
See https://service.scopserv.com/portal/en/kb/articles/how-to-make-anonymous-calls-from-a-sip-trunkOutgoing Lines | Caller ID Extension Overrides
The Outgoing Line custom ANI is always overridden if
Extension’s>Caller ID>Allow extension to override
outgoing CallerID checkbox is enabled and Emergency Calls will also take
precedence over the Outgoing Line if configured.Configuring Security with PIN Codes to Prevent International Toll Fraud
In this example you create an Outgoing Line with the Dial String rule for International (011 + digits)
And you can use the Authentication/Password drop list selector to choose Single PIN or Password List.
Single PIN is self explanatory. But if you want to configure a PIN for each user you can create a Password List in advance if you select the Password List option.
Creating a Password List
Navigate to Miscelleneous Tools|Password List and click on Add a new List
Give your list a meaningful name
Click on the Source tab to create your list and select the type of list. In this example an internal list is created with three entries.
Click Add when done and this list will be available on the Outgoing Lines|Authentication/Password drop list selector to choose it from the Password List selector.
