==Setting up LinuxMCE to use Callcentric's VoIP Service(s)==

Setting up LinuxMCE to use Callcentric's VoIP service(s) is fairly straightforward using the steps provided in "How to Properly Add Support for SIP Providers":

http://wiki.linuxmce.org/index.php/How_to_properly_add_support_for_SIP_providers

as well as Callcentric's freepbx / trixbox configuration page:

http://www.callcentric.com/support/device/trixbox

<u>Create the Callcentric Config File</u>

1. In a terminal session, make yourself "sudo su" user.

2. Since Callcentric provides VoIP based phone services using the SIP protocol, copy the Broadvoice config file as a template for editing with Callcentric's parameters:
 "cp /usr/pluto/bin/create_amp_broadvoice.pl /usr/pluto/bin/create_amp_callcentric.pl"
3. Edit the Callcentric config file:
 "nano /usr/pluto/bin/create_amp_callcentric.pl"
making the following changes:

3.1 Phone Line declaration section; change the declared host to reflect callcentric.com
 my $DECLARED_HOST = "callcentric.com";
3.2 Trunk section changes:
* <font>Change </font>channelid<font> to </font>callcentric
 $TRUNK_VARS{'channelid'}="callcentric";
* <font>Remove the following '</font>usercontext<font>' and '</font>userconfig<font>' lines:</font>
 $TRUNK_VARS{'usercontext'}="$DECLARED_HOST";
 $TRUNK_VARS{'userconfig'} ="context=from-pstn\n";
 $TRUNK_VARS{'userconfig'} .="dtmf=inband\n";
 $TRUNK_VARS{'userconfig'} .="dtmfmode=inband\n";
 $TRUNK_VARS{'userconfig'} .="fromdomain=$DECLARED_HOST\n";
 $TRUNK_VARS{'userconfig'} .="host=$DECLARED_HOST\n";
 $TRUNK_VARS{'userconfig'} .="insecure=very\n";
 $TRUNK_VARS{'userconfig'} .="nat=yes\n";
 $TRUNK_VARS{'userconfig'} .="secret=$DECLARED_USERPASSWD\n";
 $TRUNK_VARS{'userconfig'} .="type=user\n";
 $TRUNK_VARS{'userconfig'} .="user=$DECLARED_USERNAME\n";
 $TRUNK_VARS{'userconfig'} .="username=$DECLARED_USERNAME\n";
3.3 Setup Callcentric registration string.
 $TRUNK_VARS{'register'}="$DECLARED_USERNAME:$DECLARED_USERPASSWD\@$DECLARED_HOST\/$DECLARED_USERNAME";
3.4 Adjust 'routename' in ADD OUTGOING ROUTING section to "to-callcentric"
 {
     chomp;
     if($_ =~ /[<]option value[=]\"([^\"]+)\"[>]SIP\/callcentric[<]\/option[>]/)
     {
         $OUT_ROUTE=$1;
     }
 }
4. Write changes (CNTRL+O) and exit (CNTRL+X)

<u>Pulling Callcentric Config into the Web Admin</u>

1. In a terminal session, make yourself "sudo su" user.

2. Edit the provider list:
 "nano /etc/asterisk/provider_list.txt"
adding the following entry at the bottom of the list:

 callcentric     http://www.callcentric.com      callcentric     SIP
Tab between entries.

3. Write changes (CNTRL+O) and exit (CNTRL+X)
