I have installed Open-sips 1.6.0 and created 2 users at LAN ( OS Used : RHEL 5 ( 32 bit) ),
reference with URL: http://www.opensips.org/Resources/DocsTutRedhat5
Next Using X lite 3.0 sip phone i configured 2 users on 2 different Windows XP systems.
2 users were registered successfully and i am able to make incoming/outgoing calls between them.
But voice is not transmitted between them.
I tried in different ways, i couldn't make voice transmission.
What more is needed to solve this issue ?
