bearer capability not implemented

I am trying to use a Cisco AS5350 as a SIP gateway with an ATA 186 client using the SER sip server. I keep getting the following error messages?

Where should I look to determine the cause of the problem?

Thanks,

Stephen

Re: bearer capability not implemented

Based on the output above, I am guessing that you have ISDN trunks on this gateway. One possibility is that you are missing the following command underneath your serial interface for the D-channel.

isdn incoming-voice modem

Add the command and retry your call. A useful debug in this case would be debug isdn q931.
