This page describes how to register a telephone and make your first calls.

Configuring a telephone

1. Using the top-right selection box ensure you're working as your end-user customer.
2. Click on Devices and numbers » Devices and accounts » Telephone lines.
3. Click on "New" in the bottom-right corner and you'll get a form for this telephone's details to be entered. Most settings do not need changed.
4. A default telephone line number will have been provided and can be changed. Telephone line numbers are one of the few things that must be unique system-wide because when a telephone registers the system can't know in advance which customer it's referring to. So choose a telephone numbering scheme that will allow you to fit all potential telephones into your system. You can create shorter feature code numbers later which route to these telephone lines, and those feature codes can be re-used among multiple customers. So, change the telephone line number if you wish or leave it at the default.
5. Scroll down and enter a password for telephone. For security reasons it's important to have very long and hard to guess passwords. Hackers can go through millions of possible passwords in a very short period of time.
6. Enter the password again to confirm.
7. Save the telephone line.
8. Return to the list of telephone lines. You'll see a red flag for the telephone line because no physical phone has registered to this line.

Registering a telephone

Each telephone brand has it's own menu system so we can't give step-by-step instructions to set it up. But usually telephones need you to enter details something like the following:

• The SIP user or identity will be sip:<telephone line number>@<SIP proxy IP address>
• The SIP proxy address will be the SIP proxy IP address.
• The SIP user password will be the telephone line password.

Note that you can use a DNS name instead of the SIP proxy IP address, as long as you've set this up in your DNS server, and entered it in Global » Settings » Domains.

Once the telephone has registered, if you go to Devices and numbers » Devices and accounts » Telephone lines you'll see there is no longer a red flag. If you're having problems getting the telephone to register have a look at taking traces. Taking an ngrep trace on the SIP proxy server should quickly show you if a REGISTER is being received or not.

Feature codes and making your first telephone calls

1. Once your telephone is registered you can hear a voicemail login prompt by calling *1.
2. Create a second telephone line, register a telephone to that, and then try calling directly between the two telephones using their telephone line numbers.
3. Go to Devices and numbers » Numbers » Feature codes and click on "New".
4. For the first field (the feature code number) enter the last three digits of the second telephone line number.
5. Scroll down and set the default destination to be the second telephone line.
6. Save the feature code.
7. Using your first telephone call the three digit feature code number and hear the second telephone ring.
8. Create another three digit feature code which routes to the first telephone line, and try calling that from your second telephone.
