[Freeswitch-users] Why immediate hangup? Sample count too low?

[David P]

Months ago on earlier versions of FS, I added a Restart button to our verto
app which hangs-up the call and initiates a new one with a new ID. On FS
1.10.5, I notice that these 2nd calls usually immediately fail. For
example, here's one that looks fine until NORMAL_CLEARING appears.

The only thing unusual to me is the switching of the relay candidate's
address to its raddr:

Does anyone spot a reason for the hangup? Maybe the sample count is too low?
