@Pete Wells I'm currently checking the answer for your question. I'll get back to you soon.

​@Mary-Community_Moderator, I was working on another issue and came across this three-year-old post with no further details.

Hello ​@Petew, thanks for bringing this old thread to my attention! My apologies that we didn't follow up on your original query (if this is also you). Three years is a long time, and I appreciate your patience.
 

I checked our current knowledge base and resources regarding the Yealink T48s and expansion module intercom hotkey functionality on RingCentral. A lot has changed, and there are new settings or workarounds available now.

Here's the solution:

Configure the Expansion Module Hotkey (via Phone's Web GUI):

1. Access Web GUI: Get your phone's IP address (press OK button on the phone) and enter it into a web browser. Log in (default admin/admin or your specific RingCentral-provisioned credentials).

2. Navigate: Go to the DSSKey or Programmable Keys section.

3. Set the Hotkey:

   • Type: Select Intercom.

   • Value: Enter the RingCentral Intercom Feature Access Code *50 followed immediately by the target extension number.

     • Example: For extension 101, the value would be *50101.

   • Label: Give it a clear name (example: "Intercom Bob").

4. Save & Apply: Click Confirm/Save and allow the phone to reboot if prompted.

Why this works: While you set the "Type" to Intercom, the "Value" needs to tell RingCentral how to perform the intercom. The *50 code signals to the system that this is an intercom call requiring auto-answer, rather than a standard dial to the extension.

Important Notes:

• Recipient's Settings: Ensure the recipient's RingCentral extension is configured to allow auto-answer for intercom calls (usually enabled by default).

• Firmware: Keep your phone and expansion module firmware up-to-date with RingCentral-certified versions.

• Provisioning: If your phones are auto-provisioned by RingCentral, manual changes might be overwritten. For a permanent solution across multiple devices, discuss implementing this via a custom template with RingCentral support.

This setup should allow your expansion hotkey to trigger a true intercom call with auto-answer functionality. Let me know if you give it a try!
