Dear List,This is a big explanation with enough information except ngrep/ethereal captures, in both cases :ADSL Connection Speed : 512/128,ATA's : Zyxel P2002,Codec : G729,RTP Port Range : 19000-20000,and OpenSER on Public IP without NAT etc.I think i should change the ser.cfg to use MediaProxy just for SIP2SIP calls not for PSTN calls and i do not know how to do it, any clues ?Thanks,Ozan* A Side client use Zoom 4X, port forwarding to ATA in modem setting i register as port:5060 (openserctl ul show),* B Side client use Zyxel 660R, port forwarding to ATA in modem setting and register as port:10XXX (openserctl ul show),* Make a call to other sip client it's okay voice quality is acceptable most of time, but caller or callee losts ADSL connection after 30-60 seconds,* From A Side (Zoom 4X), make a call to PSTN, ADSL crashes, everything locks up,* From B Side (Zyxel 660R), make a call to PSTN, everything is normal, connection never down.ps: If i change A Side client modem to Zyxel 660R too as B Side client, the problems are totaly same.here is my basic ser.cfg >>>debug=3fork=yeslog_stderror=nocheck_via=nolisten=212.XXX.104.XXX # OpenSER Server on Public IP
