Description:I'm not sure howto classify this, but I believe this maybe related to http://bugs.digium.com/view.php?id=3963 [0003963: ALERTING not being sent for inbound PRI calls].  My setup is almost the same.

Telco ---> Asterisk ---> Norstar PBX
(DMS100)  (TE405P)  (DMS100)

Calling outbound from an norstar extension, out asterisk, to a cell phone, then hanging up before an answer, always return:

app_dial.c:362 wait_for_answer: Unable to forward frame

Attached is a PRI Trace

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

User dials 8, then a prompts plays, I then collect digits to dial.

extension.conf

[from-norstar]
exten => _8,1,Answer
exten => _8,2,callingpres(0)
exten => _8,3,SetCallerID(6132718853)
exten => _8,4,Background(demo-congrats)

include => international

Asterisk version:
cvs checkout -r v1-0 zaptel libpri asterisk

Does this still happen with head?

I don't understand what the problem is exactly;  if you hangup the call, before it is answered, this is (presumably) expected behavior.  If the voice channel is hungup, it will in affect be "unable to forward frame".

What exactly is your problem?

mattf: I am unable to test this using CVS HEAD, it is a production box.

This is actual how I reproduce the problem.  So, if I understand, it is expected behavior?  If so, I will always see WARNING: unable to forward frame message in /var/log/asterisk/messages?

Are you having any actual problems, or were you just questioning the warning message?  We need to find out if this is an expected message, and if so perhapse it should be a lower level.

MikeJ: No, to my knowledge I am not having any actual problems.  I was trying to see if the warning message was a result of a problem, but it looks now that normal operations are causing a fails warning message.

So, if my PRI Trace is in fact good, it would be a good idea to lower the messaging to stop these warning from happening.
