thanks Gary cote.

 Actually my question on SIP NAT , when we  configure our SIP client 
behind NAT setup, how will we know 'the type of NAT', the type NAT 
information where it will be present in SIP message.
so this is my question on SIP NAT.




Thanks & Regards,

Re: [Sip-implementors] Difference between SIP phone and IP phone

A "softphone" generally refers to a software-based VoIP endpoint that 
runs,
for example, on a PC. A "SIP softphone" is simply a softphone that uses 
SIP
as its signaling protocol.

An "IP phone" generally refers to a hardware-based VoIP endpoint that runs
as a stand-alone network node. As you might've guessed, a "SIP phone" is
simply an IP phone that uses SIP as its signaling protocol.

I'm sorry, but I don't understand your question. We don't describe the 
type of
NAT in SIP messages (at least, not that I'm aware of).

I'd suggest reading up on SIP NAT traversal issues and solutions. I
wish I could
be more helpful than that.
