[asterisk-users] chan_misdn and Asterisk 1.4.1 - Early B3 not working any more

[Gary Hawkins]

Hi,

I recently upgraded to Asterisk 1.4.1 from Asterisk 1.4.0 and suddenly my
early B3 seems to have stopped working.  When I call a number that is out of
service from my SIP phones, instead of hearing the announcement from the
telco, I immediately receive a SIP Busy message and the call is disconnected.
  hear no audio.  This was working fine in Asterisk 1.4.0 with exactly the
same configuration, early_bconnect options is enabled in misdn.conf, and all
other mISDN features are working perfectly, so I am not sure exactly what has
gone wrong here.  The same problem also is exhibited on today's stable branch
1.4 SVN (revision 58669).  Telco is BT, using an ISDN2e line.

Debug output from my system is available here:

Does anyone have any ideas on what has changed?

Thanks
Gary Hawkins
