The Phone  menu allows you to add SIP standard phones to the OnSIP Admin Portal for automatic provisioning. Currently, this feature supports the following phone brands: Polycom, Cisco, Panasonic, Grandstream, and Yealink. 


Creating a Phone 

In the following example, we will set up a Polycom SoundPoint 550. 

Navigate to the “Administrators” tab the select “Phones” and click "Add a Phone" 

  • You should now see a screen that looks something like the image below. 


  • MAC Address: Enter the MAC address of the phone. 
  • Make: Choose the make of the phone. In this example, it would be Polycom. 
  • Model: Choose the correct model number for the phone. 
  • GMT Offset: Choose the GMT offset (-5 for the EST, -8 for PST etc.) 
  • Company Directory: Check the Company Directory box if you want to include that in the phone. The Company Directory option will download to the phone the name and extension of all the people in your PBX. On Polycoms, this information would then be available via the "Directory" key. 
  • Easy Transfer: Check Easy Transfer if desired. Easy transfer allows users of most Polycom and some Cisco SPA phones to have faster access to blind transfer soft buttons when on a call. 
  • NAT Keepalive: Check NAT Keepalive if needed. This feature uses additional bandwidth and is only necessary in certain situations. 
  • Enable Web Interface: A phone with an enabled Web Interface is a potential security issue. Enable the Web Interface at your own risk. 
  • Phone Password: (For Polycom and Yealink phones only) The passwords of phones are changed from their default values as an added security measure. The password will be displayed below in the phone's summary. You can choose to "create a password for me" or "Use the organization's password".
  • Custom Digit Map: Enter any custom digit maps. A digit map is an advanced feature of Polycom phones. This feature is unsupported, but more information can be found here. 
  • Hit "Next" in the bottom right. You should now see this screen below, which lets you assign users to your lines. 


  • Use the drop-down menu to associate the phone with the appropriate user. You have the option to add multiple users to phones with multiple line appearances. In most cases, you will be associating one user to one phone. 

Concurrent Calls 

The Concurrent Calls check box allows that line to support up to eight simultaneous calls. If Concurrent Calls is unchecked, that line will only allow a single concurrent inbound call. If subsequent simultaneous calls come in for that line, the phone will turn away the call with a busy signal. OnSIP will then route the call to the failover location. This is a setting for Polycom phones only. 

In most cases, you will want to keep Concurrent Calls checked. 

  1. Choose "Next" in the lower right then “Finish Setup”.

Once the phone has been properly configured and the MAC address added to the interface, simply reboot the phone and it will come back up with the user automatically configured. You no longer need to go to the Web interface for the phone. 


Security Key Reset 

The security key reset is used to allow a phone that is having issues applying or reconfiguring settings proceed. 

Press the "Security Key Reset"Generate Key to reset the security key .  Reboot the phone for changes to take effect.

Configuring Busy Lamp Field 

Note on the screen below that for some phones, you can change the Lines to BLF indicators 

Line 1 cannot be changed to a BLF indicator. All other lines can be turned into BLF indicators by using the left dropdown menu. When you have toggled a line key to a BLF indicator, use the right dropdown to choose the users on your phone system you would like to monitor. 


If there is a sidecar available for your phone model, you will see the option to add it. When chosen, the additional button selectors will be visible. If you have more than 1 sidecar attached to your phone, clicking on the arrows at the bottom will allow you to configure your 2nd and 3rd sidecars. 

When done, be sure to hit "Save". 


Configuring BLF by modifying an existing phone 

In the "Administrators" tab, go to “Phones” and click on the MAC address of a phone that's already in the OnSIP admin portal and the item will expand. Click on "Edit Info " in the line details section. You should then see something like the image below. 


You will be able to select either Phone Line or Busy Lamp. If you select "Busy Lamp", the user drop-down will display all the users on your phone system that you can monitor. Remember to hit "Save Changes" when you are done. 

Once set, reboot the phone for the changes to take effect. 

When BLF users' phones are ringing, the buttons will flash. When the Busy Lamp user is on the phone, there will be a solid light next to the user. The "Busy Lamp" buttons can also be used as a speed dial to the user by pressing them. 


Changing Users 

It is very simple to move a phone from one user to another. Simply choose to modify the phone and choose the new user(s) for the new line(s) and hit "Save Changes". Reboot the phone and the phone will now come up as the new user. You do not need to delete and re-add the phone and you do not need to Factory Default the phone. 


Deleting a Phone 

Click on the trash can icon.
