Maybe you could use info on the Registrar to differentiate them: you could use some proprietary header/tag you add to the REGISTER message in case you are building both the Registrar and the UAs. > Is there any way I could add a tag name or soemthing to differentiate > between the users and include them in each message sent so that the users > can compare the tag and decide if it is for them. It doesn't seem to be a good idea to send the call to several different end-points so that the end-points resolve if the call is for them or not (it is an abuse of local and network resources). I don't get why don't you use different usernames, but if you really need this scheme, and if you mean you'll be using pjsip in both ends, then surely you can add whatever tag you want in the Request-URI or header To, etc when you call pjsip_dlg_create_uac. If you prefer, you can also add a proprietary header using pjsip_msg_add_hdr.
