Hi,
Just want to ask what is the best way to check if calls are still

Thanks
Hello
There is SST (Sip Session Timers RFC 4028), which is implemented in the
SST module, but at least 1 UA must know the extension. Also I have been
working on a IETF draft to use end-to-end OPTIONS ping to determine the
operational status of a UA.(it works well with B2BUA, relatively well
with stateful proxies). If you are interested I can talk more about the
draft and how I propose using OPTIONS requests for this.(no changes on
UAs are necessary)
