Re: change isdn channels 20 to 30

What type of gateway is this ? H323, MGCP ? If using MGCP, is the gateway registered to the callmanager ? You will also need to specify the isdn bind-l3 command under the serial interface to backhual q931 traffic to CCM. A sh isdn status, sh ccm-manager is a good start.
