> > 1. How could be differented SIP softphone 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. > > 2.When we configure SIP client as behind NAT setup, in which SIP section > describe the 'type of NAT' in SIP messages. > 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. -- Gary Cote www.awardsolutions.com _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
