[Asterisk-Users] SIP to H323 call timeout

[Fred Lee]

Hi all,

I have the following setup:

UAs ------------SER ---------- ASTERISK ----------GNUGK --------- GWs

SER is configured to route call requests from UAs to Asterisk. Asterisk is 
configured to receive the call on SIP channel and dial out to GNUGK over 
H323 channel. The problem I'm facing is that asterisk sends out the call 
request to GNUGK and times out immediately, so call setup is never 
completed. On GNUGK the call request comes in followed by a normal call 
drop.

Any ideas on what could be the problem ??

My asterisk configuration, debug and console output are as follow :

SIP.CONF
======
[general]
port = 5080
bindaddr = 10.10.1.170
context = to_GNUGK
disallow=all
allow=g729


H323.CONF
=======
[general]
port = 1720
allow = g729
gatekeeper = 64.80.103.12
allowgkrouted = yes
context = to_SER

EXTENSIONS.CONF
============
[general]
static = yes
writeprotect = yes

[to_GNUGK]]
exten => _.,1,Dial(h323/${EXTEN}@10.10.1.12:1720,60,C)

[to_SER]
exten => _.,1,Dial(SIP/${EXTEN}@10.10.1.170:5060,60)
