When getting an in-dialog REFER we get a new SUBSCRIBE-dialog. I wonder if it is mandatory to explisitly terminate (by means of "noresource") this latter dialog from the transfer target once it sends the last NOTIFY (the one with a sipfrag of 200 OK), or that it is equivaliently alright to have the transferor terminating it with a SUBSCRIBE having Expires: of zero.
The question is: is it okay to *not* terminate this SUBSCRIBE dialog but just let it timeout on some expires like a minute (handling any SUBSCRIBE with Expires: with zero from transferor)? _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
