I have a 2801 that has a 12 channel frac ISDN PRI on it programmed for channels 12-24. When i don't bind it to MGCP it comes up fine and the ISDN layer 2 status shows established. Whenever I have CCM takeover it switches between TEI_Assigned and Awaiting Establishment. The settings on the T1 controller on the router are
CCM underneath the T1 controller VWIC-1MFT-T1 is configured with the same 0 in the input and output gain. Clock: External framing and linecode the same and disabled echo cancellation. I have attached a picture of the other settings.
any help is appreciated.
