Hi *,

Is there already functionality within OpenSER to make sure that a contact is
actually alive. i.e. UA registers and slightly afterwards drops off the
network. Now when UA is called by UA2, there is silence as the SIP packets
are sent to UA -  which now doesnt exist.

I would like to implement some functionality in usrloc to do a SIP ping
(maybe using OPTIONS) before returning a contact making sure the contact is

any other ideas?
