A dialog is identified solely by the Call-ID, From tag and To tag. It makes no difference on which IP/port a stack receives a request: if it has the same Call-ID, From tag and To tag as an existing dialog, it's an in-dialog request. In your scenario, yes, the request's a valid in-dialog request. frank _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
