I have a number of Zap/ extensions defined in a queue with ringall
strategy. When this queue is called sometimes Asterisk seems to think
that one of these channels is busy, while it is NOT. The following is
shown on the console:
--Called 44
-- Called 36
-- Called 41
-- Called 35
-- Called 38
-- Zap/44-1 is ringing
-- Zap/36-1 is ringing
-- Zap/41-1 is ringing
-- Zap/35-1 is ringing
-- Zap/38-2 is ringing
-- Zap/44-1 is ringing
-- Zap/36-1 is ringing
-- Hungup 'Zap/35-1'
-- Zap/41-1 is ringing
-- Zap/44-1 is ringing
-- Zap/36-1 is ringing
While a
WARNING[165916]: File chan_zap.c, Line 3331 (zt_read): zt_rec: Unknown
error 500
is generated in /var/log/asterisk/messages
Any ideas on how to fix this?? Thanks!

Hi Michiel- This may be related to a PRI frame buffer overflow problem that I get in high-volume IVR applications. I get a lot of these errors mixed in with frame errors. In my case its load related. Mark and Martin at Digium have said they'll be looking into improving the buffering mechanism. -Scott Scott M. Stingel Emerging Voice Technology Inc.

I know... bad form to add to my own posting but: I found out that the Unknown error only appears when ringing multiple extensions at nearly the same time. When ringing two Zap channels (with &) it takes a little longer but eventually the error will crop up and one of the ringing channels will hang up.
