Instructions for Configuring a Polycom IP trunk

CONFIGURING YOUR TELNYX MISSION CONTROL PORTAL

For step by step instructions on each of the requirements on the Telnyx Mission Control Portal, please follow this guide.

Once you've configured your Telnyx account, you can now proceed to setup Polycom following the guide below.

Access the Web Configuration Utility

Connect the phone to a network with a DHCP server and wait for it to boot to the main interface. This typically takes about 1-2 minutes. Depending on the firmware version the phone has your IP may be displayed once it boots.

You can always access the current IP information by going to the following location in the menu:

Home (Button) -> Settings -> Status -> Network -> TCP/IP Parameters


Once you've obtained the phone's IP address, use your favorite web browser (Chrome/Firefox recommended) and visit the following address:

https://<phone IP Address>/

The default admin login password is '456'. If everything goes as planned, you should be looking at a page that looks similar to below.

Configure NTP Settings

While not strictly required, it's a good idea to setup your backup NTP settings in case your DHCP server does not provide time service information.

You can set this by going to the following location in the menu (red highlighted sections):

Simple Setup -> Time Synchronisation

Configure SIP Settings

Begin the SIP configuration by going to the following menu location (red highlighted sections):

You should now be on the "Line 1" configuration screen. Each line button you want to use will need to be configured individually but all should generally require the same settings. This example will show you what was required for this specific setup but your requirements may vary.

For each section listed below, you will need to enter this information (red highlighted sections):


"Identification" section:

 • Display Name (Outbound Caller ID Name)
 • Address (Your main/sub account name)
 • Label (The name listed next to the Line button on the phone)
 • SRTP settings should all be set to "No"
 • Server Auto Discovery should be "Disabled" since this is not used

"Server 1" section:

 • Address (Your selected Telnyx SIP server FQDN or IP address)
 • Port (5060)
 • Transport (UDPOnly)
 • Expires (300, your value may depend on your gateway/router timeout values but this is typically fine)
 • Subscription Expire(s) (300, same as Expires)

"Message Center" section:

 • Callback Mode (Contact)
 • Callback Contact (*97 to dial the assigned extension's VM box)

Restart and Verify Operation

To make sure that the settings take effect, I recommend you "restart" the phone by going to:

Utilities -> Restart Phone

When prompted, click "Yes".


Once your phone reboots, your display should show the phone online, the registration status section on VoIP's Control Panel should show registered and you should be able to make/receive calls with Telnyx as your SIP Provider!
