We've had a lot of problems with echo on POTS lines recently - seems the LECs are busy implementing VoIP backhaul and creating all sorts of weirdness in the local network. BRI solves this (for now) but the only gateway we have been able to find that will handle US BRI lines (switch types NI-1, 5ESS, etc.) has been to use a Cisco 2600 with a BRI WIC card and an external NT-1. All of the commercial BRI gateways we have looked at do not support North American switch types.

So

Is there a BRI card out there that supports North American switch types and will work with FreeSwitch?


<http://wiki.freeswitch.org/wiki/FreeSwitch_FAQ> says "The q931/q921 in OpenZAP will not support BRI as it stands today, and it will take quite some work for this to happen. But we have something in the plans for BRI sooner than that."

Yet <http://wiki.freeswitch.org/wiki/Openzap.conf.xml_Examples#Using_with_BRI> says "dialect can be "q931" for EuroISDN, "national", "dms" or "5ess""

I'm a tad confused...


thanks!

Look at Adtran... They have some things in the atlas series that might be
more to your liking... However it might be too large

[kurt at nv.net]

Have a number of Atlas 800 and 830 boxes here and use them all the time for PRI testing and inteop. No VoIP module for those - just confirmed with Adtran to be certain. So yes, we could use an Atlas to convert BRI to PRI, but then we need a PRI card/gateway and we are again adding a lot of parts and expense to a simple setup.

I see there might be some hope for the Eicon (now Dialogic) boards via CAPI <http://www.dialogic.com/support/helpweb/slnxen/asterisk.asp>
<http://www.dialogic.com/products/tdm_boards/system_release_software/Diva_for_Linux.htm>

Will FreeSwitch talk to CAPI?

It would be interesting to be able to support CAPI but there has been no effort as of yet.
That doesn't mean it's not a good idea, it just takes time and people and resources.
