I don't mean to be flippant, but as far as I can tell INFO-dtmf has had a better track record of interoperability than KPML. At least in the sense of (a) if you did it and the far-end did it, does it work, and (b) how many devices do it. It's an unfair comparison, because it's been around longer, and at least one very popular vendor had it deployed widely early and documented it on their website and many others were simply forced to do what they did to interoperate. Having said that, there is more than one flavor out there, and there is no negotiation. Both of those issues can be fixed with an RFC. They *are* fixed with KPML, but the cost is too high, and the solution too complicated for the problem, IMO. -hadriel _______________________________________________ Sip mailing list https://www1.ietf.org/mailman/listinfo/sip This list is for NEW development of the core SIP Protocol Use [EMAIL PROTECTED] for questions on current sip Use [EMAIL PROTECTED] for new developments on the application of sip
