I don't think the c is for check, I think its for confirm.
Yes it is, thank you for pointing this out, I now understand where my problem was for calls getting cut off.
Also as a side note for troubleshooting I find that connecting to the
asterisk console while making a call with verbose output really
helps. (asterisk -vvvvvvvr) which sets the verbosity to 7
I do this all the time, but thank you for not being afraid of staiting it.
>From www.voip-info.org on zap channels
If the letter c follows, then "Answer Confirmation" is requested, in
which the call is not considered answered until the called user
presses #.
I didn't know this, the asterisk book wasn't clear on it, I should have looked on voip-info for confirmation before I implimented it.
Are you checking to see if the line is in use?
I use
exten => _91800NXXXXXX,1,ChanIsAvail(Zap/4)
exten => _91800NXXXXXX,2,Dial(zap/4/ww${EXTEN:1})
exten => _91800NXXXXXX,102,congestion
Yes I am, thank you for this.
g: select the lowest-numbered non-busy Zap channel (aka. ascending
sequential hunt group).
G: select the highest-numbered non-busy Zap channel (aka. descending
sequential hunt group).
r: use a round-robin search, starting at the next highest channel
than last time (aka. ascending rotary hunt group).
R: use a round-robin search, starting at the next lowest channel than
last time (aka. descending rotary hunt group).
For example, if you have defined channel group 2 as containing Zap
channels 1, 2, 5 and 8, and the last round-robin search for this
group (group 2) began searching from channel 5, this is the order of
searching that the Zap channel module will use for the four possible
selection methods:
Dial(Zap/g2...): Looks in order 1, 2, 5, 8
Dial(Zap/G2...): Looks in order 8, 5, 2, 1
Dial(Zap/r2...): Looks in order 8, 1, 2, 5
Dial(Zap/R2...): Looks in order 2, 1, 8, 5
It is amazing, I have about 5 different asterisk servers around the world and I haven't spent the time to find out how this is done, thank you.
