Gtalk channel outgoing call problem

Hi
For some strange reason my gtalk channel stopped working on Asterisk 1.8.7.1 for outgoing calls creation (incoming calls work properly). This is the related configuration:
jabber.conf:

[quote][general]
autoregister=yes
autoprune=no
debug=no
auth_policy=accept

[asterisk]
type=client
serverhost=talk.google.com
username=goctala.korisnik@gmail.com/Talk
secret=********
port=5222
usetls=yes
usesasl=yes
buddy=talaganov@gmail.com
statusmessage="xyz"
timeout=100
[/quote]
gtalk.conf:

[quote][general]
context=local
allowguests=yes
bindaddr=0.0.0.0
externip=77.32.29.97

[guest]
disallow=all
allow=ulaw
context=local
connection=asterisk

[buddy1]
username=talaganov@gmail.com
disallow=all
allow=all
context=local
connection=asterisk[/quote]
extensions.conf part of context local:

Jabber debug output:

The calling attempt is from the asterisk console to the gtalk (gmail client), or extension 300. At the end it results in “CHANUAVIL”

This is a calling attempt from a sip phone:

[quote] – Executing [300@local:1] Dial(“SIP/lowpasterisk-00000013”, “gtalk/asterisk/talaganov@gmail.com”) in new stack
– Called gtalk/asterisk/talaganov@gmail.com
== Everyone is busy/congested at this time (1:0/0/1)
– Auto fallthrough, channel ‘SIP/lowpasterisk-00000013’ status is ‘CHANUNAVAIL’

Does anyone has experienced the same problem for sudden misbehavior of the gtalk channel? It seems that the gtalk server is rejecting the session.

hi, i am new to asterisk. i wish to configure it for recieving incoming calls from gtalk. After installation i do see the files jabber.conf and gtalk.conf in /etc/asterisk but in the cli i do not see the commands like “jabber show connections” i am supposed to installed another lib or the jabber daemon etc.? I also saw that make install listed installing modules from res.
