Introduction

RingCentral is a business phone system that connects employees with one solution. It offers enterprise-grade features, including auto-receptionist, multiple extensions, and more.

This SIP registration guide demonstrates three methods for integrating Algo IP endpoints with RingCentral. These methods are listed by functions within RingCentral: Paging Device, Limited Extension, and User Phones. The best method depends on the Algo IP endpoint provisioned and its intended application. The table below provides a summary of these methods, their recommended uses and limitations.

Registration Method	Description	Recommended Uses	Limitations
Paging Device	Device must be added to a Paging Group. No associated phone or extension number. Access group by dialing *84	One-way paging. Single or multi-site.	No two-way communication. No direct inbound or outbound calls. No DTMF support. No call queue membership.
Limited Extension	Registered as Common Area Phone. Can use local Digital Line phone numbers. No user-specific integrations,	Two-way communication. Direct inbound or outbound calls. When DTMF support is required.	No call queue membership. No voicemail. No advanced call handling.
User Phone	User phone with full DL capabilities. Supports call queue membership.	Call queue-related use cases. (e.g. Night Ringer)	N/A

This guide only outlines configuration details for registering Algo IP endpoints to RingCentral. For additional information on device configuration, see the User Guide for your specific Algo product.

Paging Device

Devices provisioned as paging devices do not have a phone number or internal extension. Registration via Paging Devices allows your Algo IP device to be registered to RingCentral for public announcing.

Recommend use:	Do not use for:
One-way paging (single or multi-site)	Two-way communication
	Initiate calls
	Receive regular telephone calls
	Any application requiring DTMF, such as DTMF zoning and DTMF for door control
	Night ringer

Configuration

You must open both RingCentral and the web interface of your Algo IP endpoint to register your device.

To register your device:

Log in to RingCentral and open Phone System → Phones & Devices → Paging Devices.
Click + Add Device in the top right corner of the screen.
Enter a Device Nickname, which will be the name of your SIP-enabled IP paging device within RingCentral.
Click Next to see the SIP credentials for your new device. You can also click on your new device from the screen to access these details.
Open the web interface of your Algo IP endpoint and go to Basic Settings → SIP.
Use the SIP server information of your RingCentral to fill out the following fields:
Algo IP Endpoint Web Interface Fields
RingCentral Fields
SIP Domain (Proxy Server)
SIP Domain
Page Extension
Username
Authentication ID
Authorization ID
Authentication Password
Password

Go to the tabs Advanced Settings → Advanced SIP and fill out the following fields:

Outbound Proxy	Retrieve the Outbound Proxy from RingCentral.
SDP SRTP Offer	Select Standard.
SDP SRTP Offer Crypto Suite	Select All Suites.

Make sure that the SIP Registration status is successful on the device Status page.
Go to RingCentral web admin portal and make sure the device registration status shows as (successful) in Phone System → Phones & Devices → Paging Device. Once completed, the device must be added to a Paging Only Group. A paging-only group is a collection of paging devices or desk phones that can receive a paging call.
Go to Phone System → Groups → Paging Only.
If no Paging Only groups exist, click + New Paging Only on the top right corner of the screen. Enter a Group Name and click Save.
To add your Algo IP endpoint to a Paging Only group, click on the group name in the screen and expand the Paging section. Click + Add device to Group.
Select Paging device and then select Continue. Select the Algo IP endpoint(s) to add to the group.
You can now page the connecting paging device. To do so, dial *84. When prompted, enter the page group extension number followed by #.

Limited Extension

The RingCentral Limited Extension is an extension with features limited to basic calling for Common Area Phones. This extension is not tied to a user.

Recommend use:	Do not use for:
Two-way communication using Algo IP speakers or intercoms. Initiating or receiving regular telephone calls. DTMF zoning (multicast or analog zone controller) Door control (via DTMF) with intercoms	Night ringer (call queue membership is not supported). Basic one-way paging (single or multi-site) with no use of DTMF. Using the Paging Devices method is a simpler option.

Configuration

You must open both RingCentral and the web interface of your Algo IP endpoint to register your device.

To register your device:

Go to Phone System→ Groups→ Limited Extensions.
Click + New Limited Extension in the top right corner of the screen or enable an existing one. To create a new extension, fill out the Limited Extensions and Shipping Info fields.
Navigate to Phone System → Phones & Devices → Common Area Phones. Click on an Existing Phone for the Limited Extension you would like to use with.
In the Setup & Provisioning window, select your device by going to the Other Phones tab and selecting Existing Phone.
You can now see your SIP credentials.
Open the web interface of your Algo IP endpoint and go to Basic Settings → SIP. Use the RingCentral SIP server information to fill out the following fields:

Make sure that the SIP Registration status is successful on the device Status page.

User Phone (Full Extension)

For user phones, a RingCentral full extension is possible. This creates a digital line that can initiate or receive regular telephone calls.

Recommend use:	Do not use for:
Night ringer (call queue membership is supported)	Any other application besides night ringing. Other methods are better suited for applications outside of night ringing. See Paging Device and Limited Extension above for more details.

To bind a RingCentral full extension for user phones:

Log in to RingCentral and open Phone System → Phones & Devices → User Phones.
Click + Add Device on the top right corner of the screen.
Set the requested fields as needed in the new window. When selecting a device, go to the tab Other Phones and select Existing Phone.

Troubleshooting

If you experience problems with SIP registration, follow the steps below to resolve the issue.

My Device’s SIP Registration Status Displays "Rejected by Server"

Possible Cause

The RingCentral server received SIP REGISTER packets from the endpoint but responded with an unauthorized message.

Resolution

Ensure your device’s SIP credentials (Page Extension, Authentication ID, and Authentication Password) match those configured on the RingCentral server.
Double-check that the SIP Authentication Password is correct.
1. Go to Basic Settings → SIP.
2. Click the View icon next to the Authentication Password field to display the password.
  If the password appears incorrect, your web browser may be automatically filling in the field. This can result in unintended changes when saving the configuration.
  If this occurs, correct the password accordingly.

My Device’s SIP Registration Status Displays "No Reply from Server"

Possible Cause

The device is unable to communicate with the RingCentral server across the network.

Resolution

Go to Basic Settings → SIP and ensure that the SIP Domain (Proxy Server) field is correctly populated with the server's address and port number.
Go to Advanced Settings → Advanced SIP and ensure the Outbound Proxy is correctly configured.
Change the SIP Transport Method from Auto to TLS:
1. In Advanced Settings → Advanced SIP, set SIP Transport Method to TLS.
2. In Advanced Settings → Advanced SIP, configure the SDP-SRTP Offer:
  1. Set Standard for SDP SRTP Offer.
  2. Set All Suites for SDP SRTP Offer Crypto Suite.
Confirm that any firewall in place is not blocking incoming packets from the RingCentral server.
