Hi Users,
I installed Openser server and Using the Nathelper with RtpProxy .
The openser server and RtpProxy are located in the Same system with ip add (192.168.2.2) ,
And Public IP address is xx.xxx.xxx.xxx., openSER sip_doamin name is xx.xxx.xxx.xxx
Ours Network connect for openser System is given below
modem------xx.xxx.xxx.xxx.-------------> router(firewall) ---------------------------------> server 1
|________________ > server 2
|
|_________________> server 3 ( openser and rtp )
For Testing i'm X-lite softphones with different network of openser system ( out the NAT )
When made the call from one softphone to other softphones.. When caller calls to callee , when the callee is lefted up the phone after 32 seconds the phone hungups automatically. And OpenSER is Not receive the Ack, when the invite is response and Softphones are Ringing after it lefted up . For callee only hung up
And Missed Call and Ignore Calls are working Fine ... I gucess is problem in Firewall setting in Router and System FireWall.setting . Can Any one tell me How to resolve my problem ... here is My openser.cfg
