[asterisk-r2] every 3 calls fails 1 call

[Charles Petrillo]

Hello Carlos,

Well, the versions are ok, it shouldn't be an issue.

What I meant with calling other destinations (as you say you called the call
center) if the same problem happens. Every 3 calls 1 fail?
If yes, it could be a specific channel on your trunk. Also, every E1 trunk
has a "hunting" mode for channels. It could be "even" or "odd".

Try creating a context using a dial app to call a specified channel on your
E1, so you always pickup the channel you want.

Instead of using

XXXXXXXX,n,Dial(DAHDI/g1/22222222) use
XXXXXXXXX,n,Dial(DAHDI/${EXTEN:0:1}/${EXTEN:1})

So you first digit is your channelŠ for the 10th is a dial plan with one
more X.

KR,
Charles

Hi Charles,

Asterisk 1.8.7.0
dahdi-2.4.1.2-5
libopenr2-1.3.1-0

The call center that I called have many lines, it´s never busy.

I have a PBX who comunicate via R2 to asterisk and then via R2 the asterisk
with PSTN
http://lists.digium.com/pipermail/asterisk-r2/2012-February/002426.html
(thread when I have the first problem)

The first ok call log :
http://pastebin.com/nsvZ32F2

The third call fail
 http://pastebin.com/CHGhMMe8

But it´s the same log... but diferent channel .

So I´m really lost.
