Trunk to trunk routing

We are trying to get two vodia PBX up and try connected them with site-to-site VPN connection.

My scenario is a subnet (head office) networ and a (remote office). The head office PBX is configured with two trunk, one to SIP trunk service provider and one to remote office vodia PBX.

With reference to remote office trunk setting (SIP gateway), I can make call to the head office extension from remote office phone. However, I cannot make a call to the PSTN number. Is there any options to allow to destination of incoming calls to be routed to another trunk?


pcap suggest that the destination ip of the remote office outbound call is the ip address of head office PBX.
