[asterisk-users] Subscribe Problem - Zombie Channel

[Örn Arnarson]

Hi Brian,

Did you ever figure out what's causing this, and how to deal with it?

I'm seeing the same behavior with call-pickups (it's rare, but it's
happened a few times) on Asterisk 1.6.1.11

Did you figure out a way to get rid of the channel without restarting?

Regards,
Örn
