[Freeswitch-users] freeswitch sending '481 Call Does Not Exist' in return of BYE

Wed Nov 23 12:34:08 MSK 2016

reason shouldn't make any difference.

CSec should 'increase' or just be a new one from the invite.

I see that VIA branch have changed from invite and further messages and the
bye one. I think that branch should stay the same as from the Invite.
