[Freeswitch-users] FreeTDM - any good for legacy CAS T1 protocols?

[bedgar at vseinc.com]

Bob,

I am using CAS/RBS T1’s in production now on several FS servers with Sangoma hardware to act as SIP/TDM gateways.  I have worked with Moises on a Jira, several enhancements, and configuration assistance in the past to further this along for me.  Post your questions and I will do my best to let you know what I have done.  Maybe some of it would work for you.

Subject: [Freeswitch-users] FreeTDM - any good for legacy CAS T1 protocols?

Hello all,

I have a project coming up that will require me to interface Freeswitch to some rather arcane legacy T1 protocols.  Specifically digital loop start, and station-side digital loop start.  I'm concerned that the userland support for these may be incomplete or even non-existent in FreeTDM.

I've successfully used FreeTDM to connect to PRI, but when I look for span configuration options for CAS T1, the only things that I see that may be applicable are described as "analog" options, and that doesn't sound quite right for loop start on T1 channels (but I could be wrong about that).  If I were to use Asterisk for this, I would configure chan_dahdi.conf for "signalling=fxs_ls" and/or "signalling=fxo_ls".

Should I pursue using FreeTDM for this, or would I be smarter to incorporate a simple Asterisk gateway to handle this legacy CAS T1 signaling?

    Thanks,
    Bob
