Sorry if this is a stupid question but I’m trying to understand better.
I have port 5060 People in Asia and US
(So Clients can connect to my Asterisk Server and Authenticate from Asia & US)
but I’m allowing port 10,000-20,000 in US only.
(I dont want all these ports open to Asia)
If client endpoint in US tries to talk to client endpoint in Asia
will they have communication problem?
Clients in Asia will have problems communicating with everyone! In most WAN cases it is best to assume that direct media isn’t an option, in which case Asterisk only has one pool of RTP port numbers to be used for inbound media from all sources. IVR’s will definitely not work unless all RTP ports are open.
Whilst I can’t see how it makes the system more secure, you could have two Asterisk instances, with different port ranges.
