TCP/TLS source ports
We got a SBC Acme Packet 3950 version 9.2
When a TCP/TLS trunk is configured, the SBC source port is differente from the listening port (5061).
We know this is a normal behaviour, but the doubt we have is: Which port range can the SBC use as source port? Is there a way to configure the SBC to ensure that one trunk is ussing always the same port?
We are asking this to open the ports in a remote firewall. Customer wants to open as few ports as possible.
