I have taken AIRTEL SIP PRI Line, which I have connected to my PC. Currently on my PC there are two ethernet installed where one is for SIP Calling and second is for Internet. I want to place a call from my softphone (which is connected to my Internet wifi).
I want to understand the configuration such that I can place a call from my softphone then freepbx can route it through my SIP ip.
PS: I have create a trunk, static route as well. My trunk is also getting registered. But I am receiving 503 Service unavailable.
