Configuring SIP for IPv6 support in ScopTEL PBX


IPv6 and SIP with ScopTEL PBX

Pre-requisite: you already have enabled IPv6 support on Network Configuration available on the ScopTEL PBX Web Management.

Enable IPv6 support for SIP channels

Enabling IPv6 support in ScopTEL PBX is incredibly simple. In the GUI, click on Telephony -> Configuration -> Channels -> SIP Channels and set the Bind Address (UDP/TCP/TLS) to :: (all addresses), click on Save then click on Commit to update Telephony configuration files.



The Telephony service (Asterisk) will now route SIP traffic over IPv6 for any Extensions and VoIP Accounts that have either a valid DNS record (AAAA) for their hostname, or if you specify an IPv6 address on the Extensions and VoIP Accounts.

Phones can register using IPv4 or IPv6; the PBX will translate traffic between IPv4 and IPv6  addresses and even send RTP streams between IPv4 and IPv6 addresses. This makes it much easier to upgrade the network even when some devices do not support IPv6 yet.
