MFC/R2 Configuration

 There is two methods to enable MFC/R2 with your Asterisk installation. 

• OpenR2 (Easier to install)

• Unicall  

OpenR2 (Easier to install)

-Run the command "echo "/usr/local/lib" >>  /etc/ld.so.conf" then run the command "ldconfig"

-Go to http://libopenr2.org/ and download the SVN version of OpenR2 and the Asterisk version of your choice and install them

-For a Wanpipe*.conf configuration file just simply run "wancfg_zaptel" and select E&M signaling. 

-Next go to /etc/wanpipe/ and open up the wanpipeX.conf files you just configured using the "wancfg_zaptel" script.  Change the option "TDMV_DCHAN=0" to "TDMV_DCHAN=16". 

-Click here to download a sample /etc/zaptel.conf and /etc/asterisk/zapata.conf configuration files

-If you are using Asterisk-1.4 then open zaptel.conf then change "dchan=16" to "hardhdlc=16", otherwise leave the file as is.

-That's it,  restart everything (wanpipe and Asterisk) and you'll have a working MFC/R2 connection.

This is a comment from a customer in Brazil

I've got the problem solved after several changes in the software
components used.

Just for your reference, I will summarize what I did:

• I had to downgrade spandsp library to version 0.0.2 because
  version 0.0.3 was not fully compatible with current libmfcr2
  and unicall libraries
• I had to stop installing asterisk from ports collection and
  to compile it from source, because current asterisk port uses
  a codec-negociation path which is completely incompatible with
  all versions of chan_unicall (Unicall channel driver).
• I also had to use Asterisk version 1.2.14 instead of current
  because current version also showed some incompatibilities with
  unicall/mfcr2.
