# Cisco Webex Registration Guide

## **Introduction**

Algo SIP Endpoints can register to Cisco Webex Calling as a third-party SIP endpoint for voice paging, loud ringing, and emergency alerting. This document provides instructions to set up the Algo IP Endpoints on the Cisco Webex Calling Control Hub (CH) administration portal.

All tests were conducted with the Algo 8301 SIP Paging Adapter & Scheduler, 8186 SIP Horn, 8180 SIP Audio Alerter (G2), 8128 (G2) SIP Strobe Light, and 8201 SIP PoE Intercom. These represent all Algo IP speakers, paging adapters, visual alerters, and door phones, and similar registration steps would apply.

The following Algo devices are supported with Webex Calling.

> [!NOTE]

> [!NOTE]
> **Note**
> 
> Please see certain exceptions regarding unsupported devices below:
> 
> - The following endpoints are exceptions and cannot be registered to Cisco Webex Calling, as TLS/SRTP support is not available:
>   - 8180 SIP Audio Alerter(G1)
>   - 8028 SIP Doorphone(G1)
>   - 8128 Strobe Light(G1)
>   - 8061 SIP Relay Controller.
> 
> These devices do not support DNS SRV records. For more information, please contact Algo support.
> - The 8039 and 8036 video intercoms do not support SDP SRTP encryption. Accordingly, they cannot register to Cisco Webex Calling.

## **Algo Firmware Requirements**

All Algo devices must be running firmware version 3.4.4 or later. You can verify the current firmware on the device, as well as update the firmware in the **System**→**Firmware** tab.

The latest firmware available can be checked on the website: [www.algosolutions.com](http://www.algosolutions.com).

## **Firewall Recommendations**

Before proceeding, confirm that your network has been configured as specified in the [Webex Calling services documentation](https://help.webex.com/en-us/article/b2exve/Port-Reference-Information-for-Webex-Calling). Proper configuration allows Webex Calling to establish secure and reliable communication channels for voice, media, and signaling, preventing potential issues such as one-way audio or call failures.

## Registering One Extension

### Webex Control Hub Configuration

> [!NOTE]
> Note
> 
> Refer to the article **Add Your Customer Managed Device**on [Cisco’s Webex Help Center](https://help.webex.com) for additional information.

****To configure Webex Control Hub:**

1. Log in to the Webex Control Hub as the **Organization's Administrator** and select **Workspaces**. Add the details, such as Workspace **Name**, **Type**, **Capacity,**and **Location**.
2. Click **Next**.

> [!NOTE]
> Note
> 
> If you do not save these SIP credentials, you may need to reset the password****to get a new one.
> 
> **To reset the SIP password:**
> 
> 1. Go to **Devices**, select your workspace.
> 2. Click the **Reset**icon next to the **SIP Password.**

### Algo Device Configuration

**To configure Algo devices:**

1. Log in to your Algo device’s web interface.

The device's IP address can be found by using an IP scanner tool such as [Angry IP Scanner](https://angryip.org/) which is free and open-source.
2. Go to the **Basic Settings**→ **SIP**tab. Enter the SIP credentials under **Base/Page**, as provided from Webex, following the guidelines in the table below.

| **SIP Settings** | **Value from Webex Control Hub** |
| --- | --- |
| SIP Domain (Proxy Server) | Enter the portion after the "@" of your Webex Line ID. For example, if your Line ID is jdoxdt57t9_0022EE2203C4@ca10.bcld.webex.com, enter *ca10.bcld.webex.com*. |
| SIP Extension | Enter the portion before the "@" of your Webex Line ID. For example, if your Line ID is jdoxdt57t9_0022EE2203C4@ca10.bcld.webex.com,enter *jdoxdt57t9_0022EE2203C4*. |
| Authentication ID | SIP Username from Webex. |
| Authentication Password | SIP Password from Webex. |

> [!NOTE]
> Note
> 
> - The **Extension**in this example is configured as a **Base/Page** extension. The device will auto-answer the call on this number.
> - Most Algo IP endpoints also support Ring extensions for loud ringing and alert extensions for emergency alerting. These extensions and their configurations are explained in detail in the [Generic SIP Registration Guide.](https://docs.algosolutions.com/docs/sip-registration-guide)

1. Select **Save**.
2. Go to **Advanced Settings**→ **Advanced SIP**tab.
3. Enter the **Outbound Proxy** address provided by the Webex Control Hub.
4. Set the **SDP SRTP Offer** to **Standard**.
5. Set **SDP SRTP Offer Crypto Suite** to **AES_CM_128_HMAC_SHA1_80**.

8. Call it by dialing the extension.

## Registering Multiple Extensions

### Webex Control Hub Configuration

Algo devices can be registered with multiple extensions for different requirements, such as extension-based zoning or combinations of paging and alerting needs.

> [!NOTE]
> Note
> 
> You should register a SIP extension before proceeding with creating multiple ones.
> 
> See [Registering One Exension](/v1/docs/cisco-webex-registeration-guide-2025-update#registering-one-extension).

**To configure Webex Control Hub:**

1. Log in to Webex Control Hub.
2. In the **Management**→**Devices**menu, find the recently created device and navigate to **Configure Lines**.

![A screenshot of a computer AI-generated content may be incorrect.](https://cdn.document360.io/f6f5e62d-d280-487f-9da7-5926ffd53b5f/Images/Documentation/cisco-webex-registeration-guide---2025-update-image-9s4zcu3x.png)
3. Choose another user and assign the line to it. You may have to create additional users as needed.

4. Click **Save**.
5. You will get a new **LineID**for this newly configured line.

### Algo Device Configuration

**To configure Algo Devices:**

1. Enter the **LineID**as a new **Page**, **Ring**or **Alert**extension on the Algo device. Use the same **Authentication ID** and **Authentication Password**that were created earlier.

![](https://cdn.document360.io/f6f5e62d-d280-487f-9da7-5926ffd53b5f/Images/Documentation/cisco-webex-registeration-guide---2025-update-image-6xh4fq7r.png)
2. Verify that both extensions are successfully registered on the **Status**tab.

## Troubleshooting

#### SIP Registration Status = "Rejected by Server" (in the Status tab)

**Meaning**: The Webex server received SIP Register packets from the endpoint and responded with an unauthorized message.

- Ensure the credentials (**Extension**, **Authentication ID**, **Password**) on the device match the server.
- Under **Basic Settings** → **SIP**, select the **View**icon![](https://cdn.document360.io/f6f5e62d-d280-487f-9da7-5926ffd53b5f/Images/Documentation/image(603).png)on the right of the **Password**field. If the password is not what it should be, the web browser is probably auto-filling the password field. If so, any change on a page containing a password could be filled in with an undesired string.

#### SIP Registration Status = "No reply from server" (in the Status tab)

**Meaning**: the device cannot communicate across the network to the phone server.

- Double-check the **SIP Domain (Proxy Server)** field under **Basic Settings**→**SIP** tab is filled out correctly with the address of your server and port number.
- Check if the **Outbound Proxy** is correct under **Advanced Settings**→**Advanced SIP**.
- Try changing the **SIP Transportation Method** (**Advanced Settings**→ **Advanced SIP**) from **Auto** to **TLS**.
- Ensure the firewall (if present) is not blocking the incoming packets from the server. Confirm that your network has been configured as specified in the [Webex Calling services documentation](https://help.webex.com/en-us/article/b2exve/Port-Reference-Information-for-Webex-Calling).

#### **Registration Drops Constantly**

Enable the **Keep-alive** method. Navigate to**Advanced Settings**→**Advanced SIP**, set **Keep-alive** to **Double CRLF**, and set the period to 30 seconds.
