本文介绍了如何在Asterisk中使用Dahdi通道配置R2协议，包括修改`system.conf`和`chan_dahdi.conf`文件，设置mfcr2参数，以及启用日志等，以支持不同国家的R2变种，如中国和巴西。此外，还提供了相关资源链接供深入研究。

在使用dahdi通道呼出的时候，可以在Dial中对呼出所使用的通道进行指定选择。以下面的例子来说明：

场景说明：数字板卡单E1，使用pri信令，1-31通道分配的group为1，拨号规划使用前缀9呼出。
配置文件：
chan_dahdi.conf
点击(此处)折叠或打开
context=from-insides
group=1
channel=>1-15,17-31

extensions.conf中：
点击(此处)折叠或打开
[from-insides]
exten => _9.,1,Dial(Dahdi/g1/${EXTEN:1},40)

exten => _9.,2,Hangup

一个是/etc/dahdi/system.conf。修改为如下（我一个E1卡。用一个口）：

span=1,1,0,cas,hdb3
# termtype: te
cas=1-15:1101
cas=17-31:1101
dchan=16
#echocanceller=mg2,1-15,17-31
# Global data
loadzone = cn
defaultzone = cn

Note that Indonesia has two protocols, which they call R2. One is a real digital R2 variant. The
other is more like the old analogue R2 systems. Only the real digital R2 variant is currently
supported.

然后将 /etc/asterisk/dahdi-channels.conf 追加到 /etc/asterisk/chan_dahdi.conf里面

即
# echo “#include dahdi-channels.conf” >> /etc/asterisk/chan_dahdi.conf
或者
用 vim 将 “#include dahdi-channels.conf” 添加到文件 /etc/asterisk/chan_dahdi.conf 的末尾

=========================

即
\*CLI> dahdi show channels
Chan Extension Context Language MOH Interpret Blocked State
*CLI>

================================

-asterisk –rx ‘mfcr2 show channels’

====================================

mfcr2 set loglevel debug

channel => 1-10

=============================
A complete protocol variant code is as follows:
"<country code>,<maximum ANI digits>,<DNIS digits>;"

for example:
"cn,20,7"

means use China MFC/R2. Expect up to 20 ANI (caller number) digits. Expect
7 DNIS (dialed number) digits. Most variants can handle less than the
specified number of DNIS digits, but some only handle this through fairly
long timeouts. Getting the DNIS length right can be important for good
performance.
