I'm looking for a way to do a SIP Ping on all active calls … The first thing I looked was Nathelper and nat_traversal but as far I know, they are only able to send SIP OPTIONS to see if each leg still has the connection but these modules are not able to send BYE`s to each leg if no answer is received.
Does anyone know a way to do it? The real reason to do this is to avoid locked calls, since SIP calls may hay have an INVITE with no BYE and maybe with no media in Mediaproxy.
Any idea? Any better idea?
