[asterisk-users] Chan Local, Originate and slin

[Kseniya Blashchuk]

First, I cannot set codecs with cmd Originate from dialplan (or can I?).
Second - the difference in my example is only between cmd Originate from
dialplan and Originate from a call file. To my mind, it shouldn't make any
difference.
