Cortelco Configuration

Prerequisites

Cortelco now allows public download of documentation at:
http://www.cortelco.com/manual/

Phone network configuration completed.

The following instructions assume your phone has successfully booted and completed network configuration including obtaining valid IP addresses for itself, an IP gateway and DNS servers either via DHCP, manual or other means (refer to your phone's documentation) and that your phone is running with factory defaults.

Phone is running firmware release 2.0002 or better.

You can find the firmware version your phone is currently running by logging into the phone and navigating to Maintenance. If you are running a version prior to 2.0002, please upgrade your phone's software before proceeding (refer to your phone's documentation).

Step 1: Gather information for each user.

Each user has a set of credentials which will be needed to configure each phone. For each phone that you are configuring, obtain the following:

  • SIP Address (Address of Record)
  • SIP Password
  • Auth Username
  • Username
  • Proxy/Domain

You can find this information in the user detail pages under the Users tab in the Phone Configuration section.

Step 2: Log into your Coretelco phone through a web browser

When your phone is powered on and connected to your LAN, use a browser to navigate to the IP address of your phone.

Select "Account 1".

Step 3. Enter your user information from Step 1.

For most setups, you will need to simply configure "Account 1". If you are trying to configure multiple users or multiple line appearances, you can repeat the steps below for each of the identities you are configuring.

  • Server Address: Domain
  • Authentication User: Auth Username
  • Authentication Password: SIP Password
  • SIP User: Username
  • Display Name: Whatever You Like
  • Proxy Server Address: sip.onsip.com
  • Enable Registration: Checked

Log back into the phone, navigate to the VOIP tab on the left. Enter the information as outlined above and then hit the Apply button. The phone will reboot.

When the phone is up, log back into the phone and navigate again to the VOIP tab. This time select Codec Settings.

Select the codecs to match our screenshot below

Scroll to the bottom of the screen and click "Apply" button.

Step 4. Confirm that your phone is registered.

In the Admin Portal, click on the "Users" tab. You will see a green "online" notation next to each user with a registered phone.

Troubleshooting

If you are experiencing trouble, double-check your settings as described above and be sure to verify that your password was entered correctly without any leading or trailing spaces. If you are still having problems with your phone configuration, please see our troubleshooting section for further help.
