CME - SIP Trunk - Outgoing calls delay

infologic
Level 1
Level 1

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 :

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.

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.

Hello,

Is good to hear that now everything is working

Best regards

Walter Solano.
