Добрый день коллеги, я буду признателен, если вы мне подскажете что хочет от меня заказчик:
here is a vps server on the same datacenter which has a sip server. there is already a vpn connection phase-2 established.we need configuration so that the backend and operator services can talk to eachother with SIP.the messages will run over TCP/UDP 5060 with sip peer and media will run over udp with sip-a,b,c
