I have a branch office and GW with full E1 PRI circuit and connection to IP WAN. This is centralized deployment without CCME and set-up for SRST. If the GW is not communicating with CCM (i.e. IP WAN is down), the isdn status comes up fine with multi frame establised. However, when CCM is given control to the PRI interface I lose multi frame established and see in it's place TE1_Assigned. There is no problem with layer1 isdn. As a result no external calls can be made from remote site. From CCM the GW is registered perfectly.
Anywhere in particular I should start looking?
Have already reset MGCP and GW number of times.
