I am trying to do it ovear a SIP trunk. It is the only protocol yhat the gateway GSM suport.

Just configure a voip DP with the appropriate destination-pattern, session-protocol sip, g711u an no vad.

For incoming, check what number the device is calling,you may need to translate it.

In fact I did the configuration for the dial-peer and it have the characteristics that you coment but I can't see any SIP message betwen the CCME an the GSM Gateway.

I try using the TCP port 5060 and 5061 on the GSM Gateway. It works fine on a schema CUCM - GSM but is not working with CCME

Hi, please only use 5060 and UDP with CME.

Check that you have "session-protocol sipv2" else it does H.323 and you don;t see anything.

A lot of thanks, the integration is working now. I'm using the default port onthe GSM Gateway (5060) and the mentioned parameters over the DP.

I'm just trying to give a fine tuning.

I will send you as atachment the final configuration to help futures menbers of this NetPro
