We have the Sangoma DECT phones (DC201N set) and we’re trying to get paging to work with the phones. We have the Paging Pro Module. Paging the group works for all P series desk phones as does calling *80 + extension. We can call the D10M handset directly, press and hold the call button, and speaker phone works. When paging with paging group or with *80, the phone shows the speaker icon on the screen but there’s no audio. Logging shows the connection and RTP traffic. I tried limiting the extension to ulaw but get the same issue. The FreePBX server is 17 with Asterisk 22.10 and up to date.

I suppose if you aren’t utilizing Endpoint Manager then the DECT phone’s config should reflect this being enabled. If it’s not already the case.
Configuring Auto-Answer in Endpoint Manager
- Open your PBX administration panel and navigate to EndPoint Manager.
- Select your device template used for the DC201 / D10 handset.
- Go to the Options or general settings tab for that template.
- Locate the Auto Answer parameter and toggle it to Enabled (or Enabled/Intercom).
- Choose whether to set Mute Mic (if you want the microphone muted automatically upon auto-answering).
- Save and reprovision/reboot the DB20 base station so it pushes the configuration files to the D10 handset.
We are using Endpoint Manager. Those options are not available in the template. We did enable auto answer from the handset. Intercom mode on the extension is enabled. As I mentioned, it does appear to answer but there’s no audio. I’ve run this and logs through Copilot and it suggests it’s either a codec or base station issue.
