[IAX] Does the client have to use UDP4569 as source port?
Hello
Since SIP is a bit of a pain to use with NAT firewalls in the
way between clients and *, I'm considering IAX for soft/hardphones.
One thing though: Does the client have to also use UDP4569 as its
source port when connecting to * on UDP4569, or can the client use any
UDP port dynamically, making it easy to have several phones in the LAN
behind the firewall all connecting out to *?
Thank you.
