Summary:                    1 in 3 incoming zap PRI calls do no hear audio (are
not bridged) when call is answered with agi script
Description: 
Incoming zap PRI call answers with DNIS and agi script
Some calls are answered properly with audio (bridged)
Sometimes caller hears no audio (not bridged)
Roughly 1 in 3 callers hears no audio.
No relation found to specific B channel

I'm opening as major because lots of calls are not being bridged.

Started with Asterisk 1.4.20 problem still in 1.4.24.1

zaptel-1.4.12
asterisk-1.4.24.1

The last line in the CLI keeps repeating until the caller hangs up

I can test patches after business hours and I am very anxious to get this
problem fixed; now if only someone could diagnose problem (with my debug
info) and provide patch...

I have no knowledge of C or programming skills
