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