By 'overlap sending', do you mean sending one digit at a time to the PBX and making the call when the dial string is complete? If so, no - that's not currently on the roadmap. In SIP, that's something of an "unnatural act". There is a way to do it, although I don't know how many of the phones we support can do it (because I have not checked): every digit causes an INVITE request, and any failure that _might_ be a valid number returns a special error code. Supporting this actually forces administrators to set up old-style dial plans that have unique prefix strings to disambiguate long and short dial strings that otherwise might overlap. It also adds a lot of load to the servers. The better way to do this in SIP, which requires no server support at all, is to write digit maps in your phone configurations that cause the phone to emulate this behavior locally in the phone. We don't have any way to do this automatically now, but there are people on this list who've done quite a bit of it. _______________________________________________ sipx-users mailing list sipx-users@list.sipfoundry.org List Archive: http://list.sipfoundry.org/archive/sipx-users Unsubscribe: http://list.sipfoundry.org/mailman/listinfo/sipx-users sipXecs IP PBX -- http://www.sipfoundry.org/
