I think the only way to do this is to make this yourself (tm). In your
favorite scripting language, query the locations and fire OPTIONS and
measure the time for a response (if any) on basis of the "random" callid
you create. If you route these requests through kamailio you will
prevent any NAT problems or connection with TCP endpoints.
