Hi,<br>
<br>
Just want to ask what is the best way to check if calls are still active especially when we are not handling media?<br>
<br>
Thanks<br>

Hello<br>
<br>
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)<br>
