[Asterisk-Users] Protocol Error (6) using Zaphfc

Mon Jun 28 04:56:47 MST 2004

Hei,

please never try to dial out on a particular b channel, you have to dial
out on a zaptel group which includes both b channels of the BRI line.
In a p2mp setup YOU cannot know which b channel will be chosen!

exten => _X.,1,Dial(ZAP/g1/${EXTEN})

will do....(note the 'g')....

best regards

Klaus
