hi…i need some workaround suggestion and comment about my network setup…coz im hearing information that SIP are not good for NAT setup…
My Network setup is like this:
Internet/VOIP==>NAT(win server 2003)==>Asterisk Gateway/Database==> Client PC (using SIP softphones/Eyebeam)
Currently all call are working but mostlty i ahd random disconnection, chappy voice, no ringback from client and even client cannot hear the agents call.
