[Asterisk-Users] zt_rec: Unknown error 500

[Michiel Betel]

I know... bad form to add to my own posting but:

I found out that the Unknown error only appears when ringing multiple 
extensions at nearly the same time. When ringing two Zap channels (with 
&) it takes a little longer but eventually the error will crop up and 
one of the ringing channels will hang up.
