Hi everybody,
There's a customer that has a cisco 2921 router (Version 15.2(2)T //// "flash:c2900-universalk9-mz.SPA.152-2.T.bin").
It has two FXO ports with phone lines: 1348 and 1074.
The issue is that when they make an outbound call with one line, you can't make at the same time another call with the other line.
Could anybody help me with this? What's wrong? What should be changed on the configuration if it's needed?
Regards.
Patricio

It's possible your outbound dial peer(s) are pointing to only one outbound voice port instead of a trunk group. Can you post a show run. Are they using CME or call manager?

I believe they use Call Manager.

Only 2 of your POTS lines are not in shutdown mode, can you test them individually to see if they both work?
You can build a more explicit dial-peer pointing to each voice-port individually rather than the trunkgroup and see if call goes out both times.
HTH,
Chris

I'd try removing the trunk group PSTN from the shutdown interfaces. I've run into issues with a trunk group applied to FXO interfaces that are shutdown in certain IOS trains.
Its also possible there is a physical issue with one of the pots lines. You can try pointing one of the PSTN dial peers to each FXO port and testing them seperately to make sure they are both operational.

Thanks Chris and Eric for your help!
I'm seeing the customer tomorrow. I'll try with the information that you have given me. I'll tell you how it went.
Thanks again!
Patricio
