Hi, Generally there are three ways of doing this:
1) Use SIP sever as an Edge Proxy (check rfc5626, should be a quick read) 2) Create spiral, route SIP call from proxy to your media-server and then back to proxy from media server. 3) Use SIP sever as a registrar and then forward registrations to media sever and maintaining it. (cheap way though) Regards, Salman On Thu, Dec 15, 2016 at 4:12 PM, Muhammad Naseer Bhatti <[email protected]> wrote: > > So the call hits the proxy and dispatched to the media server.
