Alcatel Unleashed

hi guys,
i have a issue with the public sip trunk. im using a SBC (cisco) for the natting. the public operator insists in using domain name (itc.sa).
all out going calls are fine no issue, but i cant receive any. when i receive a call the oxe is refusing with 404 message.
i hope some one can help me on this. i have posted the traced of ok out going and not ok incoming.

regards
Morio

the oxe did not find a sipext gw for this call.
maybe activate "Via Header_ Inbound Calls Routing" under System -> other System parameter -> SIP parameter

HI Alexik, thanks for the reply, i will try your suggestion on the site by tomorrow, will update you.

thanks again..

Hi Alexik,
done the change and even rebooted the system but still the same. I requested the provider to set the invite as same as domain. any other ideas guys. if you require more details just let me know,,

regards
morio

On the Invite i can see:
INVITE sip:+966115051030@sbc-trunking.itc.sa SIP/2.0
So it seems that the SBC has a rule that changes the domain from itc.sa to sbc-trunking.itc.sa
You can check and correct this on the sbc configuration and this should be the right to solve the issue.
As a work around, you can create an additional SIP Ext Gw for that domain

hi sadim,
@sbc-trunking.itc.sa was sent from the provider, i informed them abut this and they are now sending itc.sa for the domain in the INVITE,,, i will attach the new traces,,

thanks

these are the new traced where the provider sends @itc.sa in the INVITE

The same error in both case

hi haroun,
thanks for the reply but i dont understand it, can you please explain ..

Hi,
Change the parameter mgr-system-other syst params-SIP parameters-Loose Route with RegID to False, and try again
Note: not sure if a sipmotor restart is needed.
