Ummm, no, if it's a registering-type UAC (ie, a phone/MTA/etc.), SIP REGISTERS are typically used to keep the NAT pinhole open. That's far more prevalent than sending OPTIONS, and happens to provide several other benefits as well. When phones start doing sip-outbound, then sending STUN in the SIP port for UDP, or double-crlf for TCP, should become the new de-facto way eventually. -hadriel _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
