Hi I am planning to use a T1 card w/ Freeswitch and intend to use CAS (Robbed bit). Can someone please guide me as to what the best card/vendor would be. From what I can see three vendors support FS:

Pika
Sangoma
Digium

Any suggestion would be appreciated. I intend to use 4 or 8 T1 on a single card.

Thanks in advance

Deepak,

I've personally used T1 cards from Sangoma, Rhino, and
PBXHardware.com. They all work well. If this is a production system
then you're best off with Pika or Sangoma.

Note: CAS hasn't been tested thoroughly so you're going to be a bit of
a pioneer. I will be jumping into the fray of CAS/RBS in a month or
so. I'm definitely interested in hearing about your experiences.

Be sure to join #openzap on irc.freenode.net if you want to discuss
your setup in a real time chat.

Hi mike,

I had tried getting sangoma card over freeswitch using openzap overlay
on zaptel but I used to get seg fault. Any help on getting that
working would result in me writing a howto and including that in our
beginning an affair with freeswitch book too.

I tried making it work on e1 pri in India.

Mitul,

I recommend talking to s3g_fault on the #openzap channel. He is very clever and helped me get over the hump with a Sangoma A104D card. The FS community definitely needs comprehensive documentation for getting all of this stuff set up and I promise that I will work on it all but I won't have any time for at least another month or so. Hang in there...

Thanks Michael. I will go with Sangoma.
BTW, I read one of your postings in which you wrote:

The trick to getting openzap working with RBS is to call your RBS span
an analog span. (There are only "analog" and "PRI" spans at the moment,
and RBS signaling resembles analog signaling in that everything is
inband.)

Is this something that has been tried/made to work by someone so far?

There is a different mod now for rbs as well in openzap.

Well, MikeJ and anthm added RBS signaling support some time back. I could get RBS to work in that I got all green lights and I could see the A and B bits flipping up and down when I called a channel, but OpenZAP didn't actually have the meanings of those A and B bits programmed in the signaling. I hope that makes sense. Anyway, it is supposed to be there now but I don't know that anyone has actually tried it yet. I haven't. Definitely hop on #openzap and confirm with those guys if you're having trouble getting set up. We'll get it documented once we iron out the particulars.

do you need to do a load mod_rbs? Or is it part of the OZ package?

Ok great I shall get detailed report in a day or two.

This time I shall use tor compatible card since the sangoma card already went into on production system using asterisk.

Just wanted to ask if the PRI stack is complete or its work in progress?

It is both working and work in progress (depending on dialect). We should have some major revisions coming soon as well including timer support and eventually net side support. Note, this is in regards to both bri and pri.

I can't find any module mod_rbs or something similar in either freeswitch 1.0.1 or SVN repository for OZ. Where do I find it? Thanks

Deepak,

I was actually asking MikeJ that question. I don't believe mod_rbs exists but I was confirming. I think it's just a matter of telling your openzap.conf and openzap.conf.xml that you have "analog" spans and what kind of signaling to use in your zaptel (or wanpipe) configuration.
