Comrex ACCESS & BRIC-Link are fully compatible with sip.audio. They includes OPUS, our preferred codec for interoperability.

CONFIGURATION

Tutorial: Configure Comrex IP Codec for sip.audio

1. Log in to the web interface for your Comrex unit using its IP address, or access via KVM.
2. In 'System Settings', enable 'Show Advanced Settings'.
3. Under 'SIP Settings' or 'Alternate Modes - EBU 3326', configure as follows...
   Accept Incoming Connections: Enabled
   Use STUN Server: Yes
   Use SIP Proxy: Enabled
   SIP Proxy Address: proxy.sip.audio
   SIP Domain: sip.audio
   SIP Username: SIP Username (For example, enter fmstation.comrex for fmstation.comrex@sip.audio)
   SIP Password: SIP Username's Password
4. In the Comrex 'Connections' tab, check the SIP Status. It should show ONLINE (200 OK).
5. Ideally, under 'Switchboard Server' set the STUN Server as... stun.sip.audio
6. Consider adding a custom SIP profile as in this tutorial...
