ISDN - PRI NI2

I have a Cisco Call Manager V3.2, Cisco 3640 Router, and a Definity G3. The definity has a TN464F. We are trying to set it up so that we use ISDN PRI NI2. They still will not communicate with each other. The Cisco is setup for the

The call manager is setup with a gateway and the endpoint is setup mostly with defaults.

Is there something we are missing? When calling from ip phone we get a fast busy. When calling from a non ip we get a fast busy. If we use the Trunk access code we get a slow busy.

If you not able to get multiple frame established by doing a "sh isdn status" try placing "isdn bind-l3 ccm-manager" in the serial port for the trunk.

Example: (Sorry I had an an E1 config, should be no different)

controller E1 0/1

pri-group timeslots 1-31 service mgcp

!

interface Serial0/1:15

no ip address

no logging event link-status

isdn switch-type primary-net5

isdn bind-l3 ccm-manager

no cdp enable
