[Asterisk-Users] Unicall MFC/R2 B3,B4 and clear back

Hi All,


I have an R2 installation still undergoing testings, during the test I notice that the Unicall
always respond B6 to a II-1 (from a forward switch). Except, for a DNIS that can't be found in the
dial plan, in this case it respond with B5. My real problem is, the call will be terminate on a
Cisco 7206 with ISDN/PRI thru SIP. If the Called number is busy or the Cisco 7206 is busy or
congested, it seems there's no way for Unicall to issue B3 or B4 since its already on accepted
state. Please see the log below;

 The worst part of it, the forward switch, look lost and never respond to that clearback thus
never release the channel. 
 As a another test I called an extension with Busy as an asterisk application, it still respond
with B6.

Still, the forward switch doesn't respond with the clearback, the channel is still siezed. I don't
know, if I'm expecting B3 and B4 in the wrong place, so correct me if I am or help me if I'm in
real trouble. Thanks for your time and attention.
I paste yet another log, this time is a complete call but the called party will do hangup. Note,
it'll take 8 seconds to clear or release the channel.
