Based on the dialog id, SIP ua can identify the related dialog for incoming invite. I think SIP UA can created multiple dialogs for different users/applications.

As applicability of SIP increasing, there will be a possibility where multiple applications within a single end-user device will using SIP functionality simultaneously. My doubt if there is only one instance of SIP UA on the device and all applications are using the same SIP UA then how does UA handles routing of incoming SIP requests to different applications. E.g. co-existence of VoIP/PTT application, IM session, interactive games with in a single device like PDA and all will use INVITE requests to create or receive session. So if there is any incoming INVITE then how does UA find out what is the purpose of this invite or which application should get this INVITE for processing. Let me know if my question is all together wrong. Otherwise can somebody through some light on it? regards, -nins _______________________________________________ Sip-implementors mailing list [email protected] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors Confidentiality Notice The information contained in this electronic message and any attachments to this message are intended for the exclusive use of the addressee(s) and may contain confidential or privileged information.
