There may be a magic event you can send to do this. I can't recall if we did that for options or just info/notify. A grep for nua_options in mod_sofia dir should answer the question. Mike On Aug 20, 2009, at 11:16 AM, Michael Collins wrote:

does anybody know how to send a sip options message to a registered user, using the event socket or something else build in freeswitch i think the ping parameter does something like this for gateways.
what i want/need is the same thing that is provided in asterisk with the qualifying option, to see how "reachable" a certain client is.
Nothing exists at present but Mathieu Rene was looking at possibly adding an API to do this. Stay tuned for more information...
