I've had not luck with this either. Looks like asterisk (atleast the one
i'm using) can't understand the messages from the cisco, as i'm seeing
this in my * logs right after the call:
Mar 21 09:33:24 WARNING[196620]: chan_sip.c:6116 receive_info: Unable to
parse INFO message from DDB5CDF5-994D11D9-98DB93DC-DDF2614 at 209.96.249.5.

Could be that your calls are pstn hairpinning due to a dial peer mixup.
Saw this on our 2621 here, until i revised my dial peers. do a "debug
isdn q931" on the cisco (presuming the same command as our 26xx), if you
see the cisco sending the call back out the pri, thats what happening. I
got around this using CoS in the dialplan. If this is the case, let me
know and i can send you my solution.
