VT advantage problem

I am using CME 4.0(2) and 12.4(11)T. Trying to setup the IP comm 2.0(2) and VT advantage. IP comm works fine independently. When opening the VT advantage, it can not dial in or out and always return a fast busy tone and show a "unknown number" on display.

I tried to debug the video on CME and got the log as below. Could anyone give me a hand? Many thanks

Re: VT advantage problem

Verify whether:

Cisco VT Advantage is used

Video must be sent on the same PRI

If the new PRI Telco does not accept any bearer capability other than speech, configure bearer-cap speech under the voice port. This forces the gateway to overwrite the bearer capability as speech.

However, if video capability is necessary, request the Telco to modify the PRI to accept the Unrestricted Digital bearer capability.
