Description:This my fall under the libpri instead of zap, but here it is none the less.  I need to have asterisk be able to hand off 2 b channels of a PRI to the upstream switch.  This would get * out of the bridge and more importantly, release the use on the channels on the PRI.


Additional info on the 2BCT can be found on John Todd's website. URL is: http://www.loligo.com/asterisk/misc/GR_2BchanXfer.pdf

Please contact off-list if you need more info.  I would be wiling to place this back into community so the bounty would take that into account. In other words, give me an idea of how much!!!

So...  this is something that is negotiated with the telco switch, correct?  If both B channels originate from the same PRI * should somehow negotiate with the switch (q.931?) that they be connected at the switch side instead of through the controller (*) -- is this correct?

It uses FACILITY?? Commands.  IT does not have to be one the same PRI to work, however I believe it has to be on the same PRI group...
The document on the jtood website provides for good reading!  I wish I knew what I was READING.

Closing this, since we're moving bounties to the wiki. Please add details to

There's no amount here, start with something to get coders interested :-)

If this is too advanced for general programmers, consider discussing this with Digium directly and get a quote from them.
