Description:We have been testing app_queue in house on 1.2 SVN code for a client. We have found that SIP callers to a queue are hungup on consitently after a couple of minutes. IAX2 calls inbound to the queue can stay in the queue until answered. The message that is displayed on the console is:

"User disconnected from queue support while waiting their turn"

****** ADDITIONAL INFORMATION ******

Here is our queue config. Timings are shortened on it for testing;

[support]
music=default
strategy=roundrobin
timeout=2
retry=2
wrapuptime=2
maxlen=0
announce-frequency=10
announce-holdtime=yes
announce-round-seconds=10
context=operator
member => SIP/100
member => SIP/116
member => SIP/108
member => SIP/112

And our dial-plan logic to call the queue from a SIP extension is pretty simple;

[outbound]
; Hangup if we Timeout
exten => t,1,Hangup
include => queues

; Our Call Queues
[queues]
exten => 2,1,Queue(support)

After several tests of this using a stopwatch, we have determined that the SIP channel is hung-up after exactly 60 seconds. Are we bumping up against some time-limit somewhere?

We tracked this down to being a "polycomism". The Polycom will issue a CANCEL after 60 seconds if the call is not answered.

I'm closing this out.
