Advanced Asterisk configuration in Ubuntu …!

Posted on November 12, 2013

We will be editing the following files, each has a specific role:

  • sip.conf (domain name, Vo-IP registrar, users who can connect directly)
  • extensions.conf (extension dialing and Vo-IP inbound/outbound)
  • voicemail.conf (voice mail information)

These files are located in:

  • /etc/asterisk 

Have the following Vo-IP registrar information from your provider on hand, including:

  • SIP Main Username (ex: 2244)
  • SIP Main Password (ex: pw99)
  • DID Number (ex: 2892229999)
  • DID Point of Presence (ex: toronto.voip.ms)

Making a backup of sip.conf

Type the following to move the original sip.conf

sudo mv /etc/asterisk/sip.conf /etc/asterisk/sip.conf.orig ↵

Creating a new sip.conf and configuring it

You need to change the following for this to work properly for you:

  • Register information provided from your Vo-IP registrar.
  • externhost to your domain name.
  • [voipms] information to connect to your provider, that allows you to connect to the PSTN.

Type the following to create a new sip.conf

sudo vi /etc/asterisk/sip.conf ↵

[general]
context=internal
register => 2244:pw99@toronto.voip.ms:5060
allowguest=no         
allowoverlap=no       
bindport=5060   
bindaddr=0.0.0.0

Making a backup of extensions.conf


Type the following to move the original extensions.conf

Creating a new extensions.conf and configuring it


You need to change the following for this to work properly for you:


  • Anything with PlayBack or Background that contains “custom-*” are custom GSM files that I have created for my IVR (Interactive Voice Response) menu which are placed in the/etc/asterisk/sounds/en directory. You will need to create your own or remove them download the custom gsm files here.
  • The include lines are required for my Vo-IP register, voip.ms.
  • The [voipms-outbound] include is supplied from voip.ms which allows outbound calls.
  • The [voipms-inbound] include contains the DID provided from my registrar voip.ms which manages inbound calls.

Type the following to create a new extensions.conf


sudo vi /etc/asterisk/extensions.conf ↵
