Dear List,
SER at Public IP : 212.154.104.198 and operating good, there's no firewall or etc.
PSTN Gateway located at Public IP : 212.154.59.48 and operating good, there's no
firewall or etc.
There are two ATA's for testing purpose, both are behind NAT (Zoom X4 ADSL
Modem/Gateway) but please note that port forwarding is done from router so when a user
dials another one, the voice traffce flows directly between users, not on SER and again no
problem for parties while calling each other, they can hear/speak.
Gateway already set up to accept calls from SER's IP. When i try to dial a
cellular/landline number as i can see results from ngrep utility, SER routes the call to
Gateway and step by step it's , INVITE, RINGING... i hear ringing tone, and then
internet connection for computers/servers/voip devices in the ATA's sides are cut and
ADSL modems halts, i have to switch it off and on. after a time, not more then 10 seconds
my cellular rings, i open it and there's no voice since the connection was lost with
ATA's... Finally, i can say that routing is working but why my internet connection is
lost everytime when i try to make a cellular/landline call...
I've tried to setup a STUN Server Setting in ATA's, i've tried with a public
STUN Server 66.7.238.210:3478 again that did not solved my problem.
Anyone have an idea ?
Thanks,
Ozan Blotter
