I’m not even sure this is possible but worth asking I suppose
What we’re trying to do is route incoming calls from various DIDs to main office asterisk server and then (either through IVR or manual transfer) redirect the call to another Asterisk server at a branch office without trunking.
I suppose an analogy for this would be something similar to a HTTP redirect.
The reason for this is that we’re seeing a drop in quality when trying to pass calls via a trunk (IAX2, SIP) between offices and exploring ways to deal with it. Since it’s where our receptionists are staffed calls need to first hit the main office.
Again you’ll have to pardon me if the question is… Well… Not grounded in reality.
