[Freeswitch-users] What is "Recovery On Timer Expire"?

[Steven Ayre]

I believe it can also cover no 100 Trying reply to the INVITE.

There's also a no RTP timeout in FS(disabled by default), not sure the
cause it'll raise but it might be that one.

You might also be receiving this cause from upstream - SIP '408 Request
Timeout' response, or ISDN cause set in the Reason header.
