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.

If you have the option, try using IAX instead of SIP, otherwise you may want to get a SIP-aware firewall/router.

does NAT also affect outbound call with SIP

It can sometimes, with the inbound audio not returning inside of some networks.
