FXS SCCP ports are not receving calls

I have an EVM module in a 2821 with 8 fxs ports. I setup the 8 fxs ports as a sccp gw in my cucm6.1.. I can dial to the ip phones from the fxs port, but dialing ip-phone to fxs is not working..... what is the problem?. Transcoding?.

I have defined a media resource list for xcode with the cucm first followed by the dsp resources associated with the dspfarm @ gw.

Also I feel a timeout problem with the fxs, looks like do not release the ports after a call, some time works,some times do not work.

1. (fxs->ip phone work so so...)

2. (ip-phone->fxs do not work!!!).

Thanks for your help.

Re: FXS SCCP ports are not receving calls

To share this information with all people. My problem was the IOS doest support stcapp. I had to change the ios and implement the all remaining programming...service stcapp, sccp plar ...etc.

...

Following the cisco recomendation i setup the 1.e1-cas r2 with h323

2.fxo's with mgcp

3.fxs's with sccp.

I had to setup the service stcapp in the voice ports ..
