Maximum range for local SIP/RTP ports for Direct SIP (remote ext)

[anonymouse]

Hi,

What's the highest port we can set for local SIP/RTP ports? Per guidelines it says to +5 for local SIP port, and +20 for local RTP ports.

how many devices are you Talking about ?

Not sure on the limits, you only have to change sip / rtp ports for devices at the same location.

To make your life much easier , have you looked at installing sbc

If you want to go done stun, each device needs a fixed ip address, different sip and rtp ports and you have to setup portfowarding on the firewall
