port based nodes in SIP call flow

edit

Do you know if it is possible to make the Call Flow, to be aware of both IP addresses and port numbers and form the nodes based on IPAddress:Port information, not only IP address.

This is currently not possible, by design. Since SIP communications are almost always exclusively between hosts, and the correlation between various flows for signalling and media, i.e. SIP and RTP, is important, it makes sense to create these flow diagrams with per host nodes instead of per host:port nodes. Adding in the port number would hide the correlation between flows and make the diagram inconveniently wide as well.

To be able to support this somewhat unusual setup a checkbox option would have to be added somewhere (e.g., on the dialog) to redraw the flow diagram with port numbers in the nodes.
