How to configure Kerio Operator to connect to VOIP-Unlimited

This brief How-to describes how to connect Kerio Operator to a SIP account with VOIP Unlimited. We assume that you already have a VOIP unlimited SIP account and know your SIP credentials.

This is what you need to know:

* Your phone number and username, as provided by VOIP Unlimited

* Your password

* SIP proxy address (currently sip.voip-unlimited.net)

All of this information is emailed to you from VOIP-Unlimited.

1. Login to the Kerio Operator admin interface, go to the "Call Routing" section and press the "Add a SIP Interface" button

2. Name your new interface and enter your assigned phone number on the 1st screen; press the "Next" button

3. Select the desired internal extension (queue, script, conference or group) and optionally enter an outbound prefix on the 2nd screen; press the "Next" button

4. Enter "sip.voip-unlimited.net" into the "Hostname or IP address" field, leave the default port (5060), enter your USERNAME *not* your phone number into the username field and your password into the "Password" field

5. Tick the "User ID differs..." checkbox and enter your USERNAME into the field below, then press the "Finish" button

6. Open the route configuration again and go to the "Codecs" tab and correct the supported codecs list to match those supported by VOIP-Unlimited (Supported codecs are G729, G711a and G711u.) press the "OK" button when done
