NAT/PORT Question/Issue

[pat]

hi

every extension outside the lan needs 2 Port for SIP and RTP. So the RTP i route always one to one inside the lan.
But what about the SIP-Port's? Must this Port's all routet inside the LAN Port 5060 of the 3CX?

i.E.
Extension01 SIP 5060/5061 -> 5060
Extension02 SIP 5062/5063 -> 5060

thanks for any help.

I'm not too clear on what you are actually asking. Is this to do with port forwarding and "outside" extensions?

Other than forwarding port 5060 in your router (5090 if you use the tunnel) you shouldn't have to forward any other 5000 series port for "normal" operation. Outside extension can all use port 5060 unless there is more than one behind a router, then each will need a unique port number.

OK, that's what I don't knowing. i have only one 3CX and need only open 5060 (for SIP!).

thanks
