i don't think that pinging contacts in order to

expire if not refreshed in time. that together with limiting expires

Humm, but what about pua_usrloc?
Imagine you set your presence "offline". Using short register periods when you
generate a new REGISTER pua_usrloc will generate a PUBLISH "online" and your
watchers will see you again as online.
Yes, a solution would be to decrease the PUBLISH period in client to be
shorter that REGISTER period, but short periods of PUBLISH are not really
neccesary in "normal" cases.
Finally all this solutions would generate innecesary traffic, while a simple
unregister from OpenSer if the user doesnt' respond to ping would be
more "cheap".
i personally would not be happy my operator would
remove my registration
when my train goes into a tunnel at the as operator's proxy is trying to
ping me.
But in that case your SIP client would register again, wouldn't it?
If you are in a escenary with easy connection lost then is user task to set
the REGISTER period shorter.
Regards.
