I'm using two CCME and one Asterisk PBX.The CME Client are IPCommunicator.

When I call an extension on the first CME by the asterisk'client, the call succeeds.

But when I call another extension on the second CME, via the first CME, the call is not succeeded.

I have the same problem in the other side. I can't call any extension on the Asterisk PBX, via the first CME, by the second CME, using an IPCommunicator

Have you any idea?


PS:The debug off ccsip calls is on the attached file.

The CME will not do IP-to-IP calls if you do not use special image for that, called IP-to-IP gateway, or BSC. The image filename ends with _isv. With that, you configure "allow-connections sip to sip", codec transparent on the DP, and you should be able to call.

If you cannot do that, build IP connectivity between asterisk and the second CME, and call directly.

Hope this helps, please rate post if it does!

But I have a question.

Do this feature can resolve this?

"Multiservice IP-to-IP Gateway with Media Flow-Around"

In other case, do Advanced Enterprise can resolve this?

The old IOS is a c1841-spservicesk9-mz.123-8.YG4.bin

And the planed is :



Have you any idea.

Thank you.

Yes, that the one. Yo do not necessarely need to do flow-around.

I'm not sure exactly in older IOS which images have the feature if any. For the 12.4(11)XJ3 that is what you want for advanced voice interworking, you need the _isv image. I don't think it's available with the 1841.

I know that 1841 is not for CME, even if it support the telephony service.

But I wanna try if it can do gateway for voip.

Ok, I'll try to seek this image.
