Provisioning extensions in a simple way

To check if our extensions are correctly configured, we will set up a softphone (a software emulation for a phone) called Zoiper that supports the IAX2 protocol. This software can be downloaded from http://www.zoiper.com/. We will also use an SIP IP phone. In this case, we will use model 6739i from Aastra.

Most of the time when configuring any IP device, we need to know the following parameters:

  • Extension Number or SIP Authorization Name or SIP User
  • Password
  • IP address or host to which our device will register SIP Port, generally port 5060 in TCP/UDP

How to do it…

  1. To configure our softphone, we will introduce the following values to the corresponding parameters or fields as follows:

    Username: 7004

    Caller ID Name: IAX2 Extension

    Caller ID Number: 7004

    Server Hostname/IP: 10.20.30.70

    Password: 1234abcd

    In other words:

  2. If the parameters were correctly input, we will see the next picture confirming that our extension is registered to the PBX and is ready to make and receive calls:

  3. To configure the IP phone (Aastra), enter the following values in the corresponding fields by accessing its configuration settings via the Web:

    User Extension: 7003

    Display Name: SIP Extension 7003

    secret: dfgty7834c

    Server Hostname/IP: 10.20.30.70

  4. In both cases, confirm that the devices were properly configured and registered to the IP-PBX, either in the PBX | Operator Panel menu (next screenshot) or by just making a call between them.

  5. Dial from the IP phone (extension 7003), and our IAX2 extension (7004) will ring. If we can establish a normal conversation, we can conclude that we completed these steps successfully. Once the call is established, we can check its status in the IP-PBX in the PBX | Operator Panel menu as follows:

  6. Finally, repeat this process for all the extensions that we need to deploy.

    Tip

    It is very important to read the operation manual of all devices involved in your IP solution, in order to configure them properly and take full advantage of their features. For softphones, we must have a headset connected to our PC or laptop.
