Does anyone have some real-world experience with SIP OPTIONS PING? Our softswitch vendor is looking to implement support and seeking some input on check frequency, response timeouts, how quickly to check recheck on a down, and how long to wait after it's up before restoring the SIP trunk group. And should there be a ramp-up period through some kind of rate-limiting? If you have a product that does it well, what parameters does it use? How do you think the software should handle existing calls that may or may not have active media flows? Should it tear down calls immediately, use some kind of active media detection, or wait x minutes before tearing down calls? Any input here or offline would be appreciated. Kind regards, Frank
