My Idea:
So My Idea:
DC Server:
IAX2 connection to office server: type=user This should allow the DC server to use make use of extensions that are in the office server dialplan, in this case the agent's extensions.
On this server is a context that call's coming from the office server via an IAX2 connection, are placed into. In this context I would declare extensions to allow agents to login, and to check voice mail left by those who have timed out of the queue.
Office Server:
IAX2 connection to DC server: type=user This will allow agents to connect to the DC server for login, and VM checking.
An IAX2 connection for the DC to connect to this server that places incomming connections from the DC into the local extensions context.
I don't know if there is something that I really don't get, but my understanding of IAX peering suggests that this should work.
