My main caution on anything related to interoperability between codecs and different brands of equipment is this:  While you may be able to "get them to work together", you may only have one single, bare-minimum WAY that they will work together. 

 

For example, to connect into our Comrex Access from a Telos Z/IP One, the only method we've found successful is G.722 via SIP.  It works, and sounds better than a phone line, but you don't get all the "auto-breathing" bitrate adjustment and forward error correction, etc. that you would get using a native Comrex-to-Comrex or Z/IP One-to-Z/IP One connection.

 

TL/DR:  It's best to match brands of Codecs for the most features and best results.

 

Thanks,

Brian

I asked a similar question, the answer is Yes I believe for comrex. Below the response, note that I sked about “Calling in” to  a telos VX.

 

“Short answer: If the receiving codec is set to answer a SIP call, we have codec interoperability utilizing the SIP Standard.  I'll detail further below, but I do not have any information on the specific codec you've specified.

 

You can make IP connections to other manufacturer’s codecs if the SIP protocol is used on both ends and the codec you are connecting to is EBU N/ACIP Tech 3326 compliant. The following parameters will need to be set on both codecs. Try the following setting, once connected; you can try other settings as desired.

Profile     mono

Bit rate   64k

Algorithm   G.722

Session port  5060 TCP

Audio port    5004 UDP

Below are links to information about compatibility to other manufacturer’s codecs using SIP and ISDN for the G5 family of codecs including the Merlin and Genie codecs as well as the G3 family of codecs.

Subject: [CRTech] TIE LINE AND COMREX COMPATIBILITY

 

We have 2 Comrex / Brics at our Studio and use a Comrex Access for an occasional remote. ( the Access is the older unit with the small screen and stylus).

we have been considering purchasing a second Comrex Access and I saw the new Access NX ( newest Version) at NAB. I like this unit much better but I also looked at the TIE LINE VIA. WOW!
 

I really Like the Tie Line features much better for what we have planned however I cannot afford to purchase the Tie line Merlin that goes with it.

Does anyone know is there any possible way a Tie Line can Communicate with a ( Comrex)  Bric. I realize these are competing companies and no one would support it, But I need to decide which of these units I'm going to purchase soon.
