Delay outbound calls sip trunk

[Ansik]

Hi ,

When i make an outbound call there is a delay of 25 secs. Inbound calls are instant.

this is the scenario IP Phone --> CME --> SIP Provider

dial-peers are very simple yet i still get a delay.

attached debug voip dialpeer inout and dial-peers and running config modified.

Thanks

The logs are not helpful. Take the following for a problematic call -

debug ccsip message
debug ccsip error
debug voice ccapi inout

Hi,

Please find attached log

I think your issue is related to the domain lookup. Why are you using a domain in the sip-server when all you are doing is hosting the entry on the router itself ? Why the additional stack lookup on the router ?
Remove the sip-server target from the dial-peer 1 and configure session target instead with the IP of your ITSP and then test.

configured dial-peer 1 as below and outbound now fails. I configured the domain lookup because isp expects " customer@sip.isp.sr " to register ,registration as " customer@10.150.3.11" was failing

dial-peer voice 1 voip

Did you remove the registrar config as well from the sip-ua ? You only had to remove the sip-server.

no did not remove the register config. removed the sip-server from the sip-ua.
call still failing.

I noticed the sip trunk does not register when i remove the sip-server from the sip-ua.

Lowering the ios to 15.1(2)T4 solved this problem.
