CME - SIP Trunk - Outgoing calls delay

Hello,

I have a Cisco 2801 directly accessing the Internet via a public IP address and it is working fine, I can make or receive calls with no problem. I then moved the 2801 inside of my local network and tried to use it the same way. The fact is I can receive calls with no problems but when I try to place and outgoing call the phone dials but wait for almost a minute with no tone or anything. Then around one minute later the call is made, I don't think this is an interdigit timeout problem given that the phone actualy dials the number.

My configuration is as follows :

Re: CME - SIP Trunk - Outgoing calls delay

Hello,

I would like to know if you already tried to use IP address if you ITSP under the sip-ua configuration instead of the FQN, just to disscard any issue with the DNS resolution taken so long.

Also I would like to see the output of the debug ccsip messsages and ccapi when doing the call.

Re: CME - SIP Trunk - Outgoing calls delay

Hello,

Thanks for your answer, it was indeed the dns resolution taking too long, I changed the dns-server adress and everything works fine. Once again thanks for the fast answer.
