I have the below scenario.
One of my companies is having PBX & the other company is having Cisco CUCM.
I want to make SIP trunk between these 2 so that each company can communicate over VOIP.
Below are my queries.
- Company A PBX & the company B CUCM are in the same network.
- So I am planning to use NAT for the communication between them. It will be double NAT
- The end phone systems of company A & company B can communicate with each other (No NAT required)
In this scenario, if I make sip trunk using NAT (double NAT) will it work.
Will sip trunk under double NAT will work ?
