Domain names would be a good idea, but they are not required to use provisioned connections - you can provision one or more IP addresses almost as easily. Registration was designed to route calls to _a_ contact - it is a misapplication of the mechanism to use it for any more than that, and that's where the difficulty comes from. It's a mystery to me why this is so commonly used (yes, I know it is, and the sipXecs SIP Trunk support can do it). Why would I want the reliability of my inbound calls to be controlled by my system having to 'poll' (that's effectively what a registration is) rather than the provider just knowing where to send it? _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
