Summary:                    channel appear as UP before call being picked up
(and wrong indication in CDR)
Description: 
Hello,

First of all, nice work on the xmpp/gtalk support as a first approach to
support jingle.
My first bug report here, so if something is missing (or wrong) please let
me know.

In all my testing scenarios with established calls everything seems to be
working ok - including the audio (but  I tested only with the gsm codec).
The problems I detected seem to be more related to signaling when the call
do not go through because one party ends the call before it being picked
up.
Please read bellow a detailed description:
 
1) PROBLEM: Channel appear as UP before call being picked up (and wrong
indication in CDR)
 
Testing components: 
- Fedora core 3 + Asterisk server 1.4.10 (no zaptel, no libpri) + iksemel
1.3 (also tested with 1.2)
- 1 google talk credentials for asterisk server connection
- 3 clients on different PC’s for testing: 1 zoiper iax client
(IAX_CLIENT), 2 google talk clients (GTALK_CLIENT_1, GTALK_CLIENT_2)

Testing Flow: Clients trying to call each other (once at a time) and one
of the parties ending the call before the call being picked up.
 
In the next points I will detail the problems according to the direction
of establishment of the call:
 
1.a) IAX_CLIENT -> GTALK_CLIENT_1
 
In both the following situations:
- call is disconnected by the IAX_CLIENT before the GTALK_CLIENT_1 pick it
up
- or call being rejected by the GTALK_CLIENT_1
the channels appear always as UP (“show channels”) and in the CDR (in
the end of the call attempt) appears as “ANSWERED”. This is not
correct.
 
1.b) GTALK_CLIENT_1 -> GTALK_CLIENT_2
 
In both the following situations:
- call is disconnected by the GTALK_CLIENT_1 before the GTALK_CLIENT_2
pick it up
- or call being rejected by the GTALK_CLIENT_2
the channels appear always as UP (“show channels”) and in the CDR (in
the end of the call attempt) appears as “ANSWERED”. This is not
correct.
 
1.c) GTALK_CLIENT_1 -> IAX_CLIENT
 
In both situations:
- Call is disconnected by the GTALK_CLIENT_1 before the IAX_CLIENT pick it
up
- or call being rejected by the IAX_CLIENT
the channels appear only as Ringing/Ring (“show channels”) and in the
CDR (in the end of the call attempt) appears as “NO ANSWER”. So, in
these situation everything seems to be OK!
 
The problem in this last scenario is that when it is the IAX_CLIENT that
rejects the call the GTALK_CLIENT_1 keeps ringing until it goes to the
google voice mail. (It seems not to be notified about the call end)
When the call is rejected by the IAX_CLIENT in the asterisk CLI appears:
[Aug  9 17:34:08] NOTICE[21377]: chan_gtalk.c:1371 gtalk_indicate: Don't
know how to indicate condition '-1'
  == Auto fallthrough, channel 'Gtalk/rpinto-12d3' status is
'CHANUNAVAIL'
[Aug  9 17:34:08] NOTICE[21377]: chan_gtalk.c:1371 gtalk_indicate: Don't
know how to indicate condition '8'

ahhh... another question :)

How do I know if this correction of yours is included in the next asterisk
release?
