GENERAL INFORMATION
Asterisk (and Asterisk@Home) is an extremely powerful piece of open source software which allows you to run a full-featured software based PBX on your computer. Typically Asterisk is run on Linux, but it has been known to run on Mac OSX and in some cases even Microsoft Windows.

Asterisk is extremely powerful and versatile, but requires dedication to get it up and running. Asterisk is NOT plug and play software; and because of its extremely versatile nature is typically difficult for first-time users to setup.

Below we have listed resources to help you in configuring Asterisk (or Asterisk@Home); as well as a basic setup guide for Asterisk. Because of the complexity of Asterisk we cannot provide detailed support in helping you get Asterisk running; but you can find help from many Asterisk experts in the resource list below.

Please note that Callcentric is not responsible for preventing unwanted physical or remote access your IP PBX. If your IP PBX is compromised then you will be responsible for any damage caused.
Please be sure to read this guide regarding securing your IP PBX solution.

BASIC Asterisk CONFIGURATION FOR CALLCENTRIC

STEP 1 Setup trunk and global options:
Edit the sip.conf file with your favorite text editor and make the following changes:

  • Add/change the [general] section with the following parameters:
    [general]
    dtmfmode=rfc2833
    context=from-callcentric
    srvlookup=yes
    register => 1777MYCCID:SUPERSECRET@callcentric.com
    

  • Add the following section to define the Callcentric trunk/peer:
    [callcentric]
    type=peer
    context=from-callcentric
    host=callcentric.com
    fromdomain=callcentric.com
    username=1777MYCCID
    fromuser=1777MYCCID
    secret=SUPERSECRET
    insecure=very
    canreinvite=no
    disallow=all
    allow=ulaw
    

  • Add an extension to handle calls to/from your SIP phone. This is just a sample. Refer to Asterisk documentation and your SIP phone documentation for details. 123 is the extension of your phone.
    [123]
    context=to-callcentric
    type=friend
    username=123
    secret=PASSWORD
    host=dynamic
    
  • Make sure to save your changes once done.
STEP 2 Edit the file extensions.conf:
  • Add the following section to route calls FROM callcentric TO your SIP phone with extension 123:
    [from-callcentric]
    exten => s,1,Dial(SIP/123)

  • Add the following section to route calls FROM your SIP phone TO callcentric:
    [to-callcentric]
    exten => _X.,1,Dial(SIP/${EXTEN}@callcentric)
STEP 3 Verify Asterisk operations
  • Connect to asterisk console by running the following from the command line:
    asterisk -r

  • Verify that Asterisk is registered to callcentric with console command 'sip show registry'
    *CLI> sip show registry
    
    Host                    Username    Refresh	State
    callcentric.com:5060    1777MYPHONE 17      Registered
    

  • Verify that your SIP phone is registered to Asterisk with console command 'sip show peers'
    pbx*CLI> sip show peers
    
    Name/username   123/123
    Host            10.11.22.33
    Dyn Nat ACL     D
    Mask            255.255.255.255
    Port            5060
    Status          Unmonitored
    

    If you see Host as "(Unspecified)" and Port as "0", then your SIP phone is not configured correctly.

  • Disconnect from Asterisk by typing exit.
STEP 4 Placing Test Calls
You can make a test call to 17771234567, or if you are signed up for one of Callcentric's rate plans you can place a call to a traditional landline or mobile phone by dialing either:
1 + the area code and number for calls to the US
Or
011 + the country code, area code, and number for calls worldwide (you may also use 00 instead of 011).

To test inbound calls from Callcentric to your Asterisk installation, follow the directions listed in this FAQ.
