External calls from SRST branch office

Hi all,

i have an issue in the branch office where i configured a 2811 router as SRST. all IP Phones register to the CCM in the headoffice. the WAN link from the head office to the branch office is 512kbps. the 2811 router does not have an FXO or E1 so all external calls from branch office go the VG at the HQ.

when external calls are placed to PSTN numbers from the Branch office it rings on the mobile and when its pick there is no voice communication. it just a dead end on both sides. but directory number calls from branch office to HQ is successful and both parties can exchange clear voice communication

i thought its a routing issues and i have fixed all the routing issues.

i created 2 Vlans on the SRST router 1 for data and 1 for voice.
