Outgoing calls not happening on SIP trunk

I have created a SIP trunk in CUCM 6.1 and created a route patter for ISD dialing, whenever i dial any ISD numbers i don't hear any ring back or dial tone, and after some time the call gets disconnected. SIP trunk has a public IP towards my service provider. I have check point firewall which has this public ip and opened all the UDP ports and also the SIP port 5060.

I pulled out SDI and SDL logs and found the below error

(102) Call terminated when timer expired; a recovery routine executed to recover from the error

and in the log details i got the following information

07/27/2012 16:44:03.046 CCM|//SIP/SIPUdp/wait_SdlSPISignal: Outgoing SIP UDP message to 202.x.x.x:[5060]:

Outgoing calls not happening on SIP trunk

I agree with Inder, and is more secure to use a CUBE.

You can configure address hiding, trust list and other things. Check the documentation.

Outgoing calls not happening on SIP trunk

I have attached the wireshark logs, also i checked on NATTING part everything looks ok. But still the problem persists, as per the service provider they are getting CUCM trigger on there gateway.

Re: Outgoing calls not happening on SIP trunk

Still No Luck on this issue, i have captured packet traces from the CLI of CUCM and gone through it from Wireshark, i am getting a traffic from my firewall and whenever it hits the CUCM IP it shows error 404 not found.

Re: Outgoing calls not happening on SIP trunk

HellO !

I would like to know about the following check list.

A) Did you add domain name in the router ?  Is yes. Please go and add domain name in the Gateway and trunk settings?

like : Nameoftherouter.domainname

B) R u getting incoming from from all pattern ? ex: ,local, STD,ISD'

    If yes. Double check did you configgure pattern with correct predigit dot seltion at the pattern level /

    If yes. Double check ? Did your call router configure outgoing pattern and dial rule/

   Sample. If in INDIA

 

dial-peer voice 8000 voip

destination-pattern  (DID) $

session protocol sipv2

session target ipv4:callmanager IP

incoming called-number .

dtmf-relay rtp-nte

codec g711ulaw

no vad dial-peer voice 8000 voip
destination-pattern DID$
session protocol sipv2
session target ipv4:Call manager IP

incoming called-number .
dtmf-relay rtp-nte
codec g711ulaw
no vad

More support open case in cisco ?

Thanks

Re: Outgoing calls not happening on SIP trunk

Hi Everyone,

This issue has been resolved, i just added SIP trunk in our new MCS server which has 8.6 CallManager version and we are able to make ISD calls for US and Canada, i wonder why this has not supported in 6.1 CallManager. May be some bugs related to SIP behaviour. Also in 8.6 we have an option for enabling SIP early offer settings, may be this also one of the reason. Where as 6.1 is not having any settings for SIP early offer and delay offer.

Thanks for your support
