4 p.m.
Conditions as follows :
* SER runs on a Public IP
* SER works without auth & database modules,
* Nearly all user behind NAT (but routers configured to do port forwarding for TCP/UDP
5060) to help SER in some cases,
* Users numbers in format of 833XXXXXXX 834XXXXXXX and they should call each P2P-SIP-Calls
(if not behind NAT),
* If a user need to call PSTN end point (SIP Gateway located at 212.154.32.154) the call
traffic should flow over SER to SIP Gateway via T1 connection already located between that
systems so SER handles all voice traffic by help of RTP Proxy.
* UA's registers on SER (Zyxel Prestige 2000, Zyxel Prestige 200W, Cisco ATA186 etc.)
Problem is users cannot call each other (if i comment lines for nathelper they can call)
It's clear i think, and below is my ser.cfg, what do i need extra or erase. (It was
successful without nathelper module and added dial plan)
I get this error :
