This guide is a detailed and comprehensive guide to provisioning a Polycom phone with your Switchvox. Polycom PBX,  if you have any questions about providing a Polycom phone with your Switchvox, this guide will walk you through the same process.


This archive will guide you through the steps to resolve most problems with Polycom and Snom phones that have not been appropriately provisioned using the Phone Setup process. If you call Switchvox Support, these are the steps that a delegate will guide you through. Polycom PBX,  this guide is easy to follow if you don’t mind.

Before we start the investigation process, there are a few things that we need to know and discuss.

Remote Phones: These telephones are not connected to the same organization fragment as your PBX. This could be different subnets, VLANs, or telephones that are genuinely located in an unreachable area than the PBX. Polycom PBX,  although remote phones can be taken via the telephone arrangement process, we want to ensure that all correspondence ports are accessible on all organizations and organization fragments. This association traffic does not go over. These ports are essential for a telephone to connect from a distance with your SwitchvoxPBX.

UDP 5060

UDP 10,000 – UDP 20,000

These ports must be accessible to the organization associated with the telephone. Therefore, traffic over these ports should be sent directly to the IP Address for your PBX at the organization with which it is associated.

VOIP Network Features: Many devices, including switches, firewalls, and a few switches, have features designed to help with VOIP traffic. Polycom PBX,  these highlights can be helpful, but experience has shown that they can sometimes cause VOIP correspondence or telephone enlistment problems.

Here’s a list of VOIP highlights Switchvox may have experienced in the past.

SPI (Stateful Package Inspection)

Taste Transformations

Taste ALG (SIP Application Layer Gateway)


NAT Filtering

Taste Inspection

Shrewd Packet Detection

Switch to Choice 66

These highlights should be imposed on all organizations that have them.

Existing Phones: If telephones are associated with your Switchvox, we must confirm that they can be made/receive calls to them. If the telephones that are currently connected to your Switchvox PBX do not work, this could indicate that there is a bigger problem.

If some telephones associate with the PBX, but others are not. It is necessary to identify whether they are not in our vicinity or far away from the PBX. Polycom PBX,  we will also need to assume that the new telephone we are trying to enlist has a nearby or distant location. Like where all telephones do not enroll to the PBX, it is minimally essential to try to interface with another nearby or remote phone, assuming that all other phones associate with the PBX.

If this is the primary telephone we associate with Switchvox’s PBX, we strongly recommend that you use a private phone.

Arranged Phones: If you’ve tried to get this phone through the Phone Setup interaction but failed, the chances are good that the current telephone’s MAC address has been moved beyond the Unknown Phones section of the Phone Setup Page. Polycom PBX,  before we begin investigating the steps to manage the phone, we need to reset any progress made in the Switchvox programming regarding Phone Setup.

It’s possible to check in the Switchvox web point of interaction System Setup > Phone Setup. If we find the telephone in either of these rundowns, please snap on the checkbox to the right of the MAC Address. Next, click on the red “Reject checked phones” or “Unconfigure checked phones” button at the top of the page. Polycom PBX will take the phone back to the Unknown Phones List.


Once we have verified that the phone company opens the appropriate ports to reach your PBX and the current telephones are enrolled (if any), we can now focus on the particular phone we are having difficulty with. Below, in numerical request, are the steps Switchvox Support decided would allow us to take your phone through the Phone Setup process.

1. Initial steps in the investigation system include resetting the telephone to its default processing plant settings.

Polycom Directions

Press the Menu key on your telephone and then select the following options: Settings > Advanced>> 456 (the default secret phrase), Enter > Admin Settings, Reset to Default.

Although there are three options in the menu, we will only use two. “Reset Device Settings” and “Reset Local Configure,” respectively. Polycom PBX,  please reset your device settings first. After selecting each reset option, the phone will reboot. Although it may take a while, it will restart if you are patient.

The reboot process can take up to ten minutes. During the phone’s boot interaction, you’ll see various messages on the LCD screen. These messages include “downloading the app,” “can’t reach boot server,” etc. These messages are standard and do not cause any inconvenience.

The telephone will stop restarting when the date and time appear on the LCD screen. Please note that an unacceptable date and time might display, but this is normal. Suppose you don’t mind following the above instructions. Then select “Reset Local Configure” After selecting the reset option, the phone will restart. If the reboot process is not too complicated, wait for the phone to complete before you continue.

Suppose restoring the phone to its default settings causes the telephone to reboot constantly. We will need to power the phone to download new design documents from Switchvox PBX. We will then play out a couple of investigating requests to accomplish this.

Virtual Telephone

* We want to make sure that Switchvox programming understands that it must push programming to this phone. Therefore, we recommend that you ensure that this telephone’s MAC Address remove from the “Unconfigured” and “Design Phones” lists on the Phone Setup page. The telephone’s MAC address should record in the “Unconfigured Phones” list to stop the reboot cycle. In addition, the phone should list as “Obscure.” We can examine the container and click the “Affirm check Phones” button to confirm. If the MAC Address of the telephone appears in the “Arrange Phones” list, please refer to the Configured Phones section at the top point of the archive to return it to “Obscure.” Then, we can confirm the telephone and move it to unconfigured.

MAC Address

* If the MAC Address of this telephone does not appear in any of the Phone Setup menus, then the Switchvox PBX cannot be used to stop the boot cycle. There are two options. You can use your FTP server to add arrangement records to the telephone or contact Switchvox Support to discuss other options.

* The telephone will reboot at a time when the LCD screen shows “Welcome,” and the “Arrangement” button should select. When you press the arrangement button, you prompt to enter a secret code. Which is 456, and then take to the Network Configuration menu options for the telephone.

* The telephone should start downloading design documents from PBX as soon as it restarts. The time and date should appear on the LCD screen when the phone finishes restarting. (If the date and time are incorrect, don’t be alarmed. This is normal). Polycom PBX,  we should be able to close the phone setup by going through the Phone Setup. This will ensure that the telephone is communicating with the PBX efficiently.

* In the unfortunate event that the above advancements have failed to remove the telephone from the endless boot loop. We find ourselves again. For any query, visit My Country Mobile &Telecommunication Marketing
