Support / Voice / Phone / Sangoma

Configure Sangoma IP phones for VoiceTel.

Sangoma desk phones — S-series (S205, S305, S405, S505, S705, S715) and the newer D-series (D60, D62, D65, D80) — share a common SIP account configuration menu. The web UI is the simplest path; Phone Apps / EndPoint Manager is the right path for FreePBX-managed fleets.

Web UI configuration

  1. Find the IP address: press Menu → Status → Network.
  2. Open http://<phone-ip>. Sign in (default admin password is printed on the phone's barcode sticker; change it on first login).
  3. Open Account → Account 1 → General.
  4. Set:
    • Account Active: Enabled
    • Display Name: caller's name
    • SIP User ID: SIP username from VoiceTel onboarding
    • Authenticate ID: same as SIP User ID
    • Authenticate Password: SIP password
    • SIP Server: the SIP server host shown in your customer portal
    • SIP Port: 5060
    • Outbound Proxy: the SIP server host shown in your customer portal
    • Transport: UDP
    • Server Expires: 360
  5. Open Account → Network:
    • NAT Traversal: Keep-Alive
    • NAT Keep-Alive Interval: 30
  6. Open Account → Codec. Enable PCMU, PCMA, and G.729; move PCMU to the top.
  7. Open Account → SIP → Advanced:
    • DTMF Type: RFC 2833
    • RFC 2833 Payload Type: 101
  8. Click Save; the phone reloads the SIP stack and registers within a few seconds.

FreePBX EndPoint Manager / Phone Apps

If your downstream PBX is FreePBX (or PBXact), the Sangoma Phone Apps service auto-provisions Sangoma desk phones with FreePBX-managed extensions, line keys, and BLF presence:

  • Activate the Phone Apps module in FreePBX.
  • Add the phone's MAC under Connectivity → Endpoint Manager → Add Extension Mapping.
  • The phone boots, contacts FreePBX over HTTPS, fetches its config (including the VoiceTel trunk's outbound route), and registers as the assigned extension.

For trunks pointed directly at VoiceTel (no FreePBX in the middle), use the manual web-UI steps above.

Auto-provisioning (non-FreePBX)

S-series and D-series phones support standard HTTPS auto-provisioning. The phone fetches a per-MAC cfg<mac>.xml file from a configurable provisioning URL. Contact VoiceTel engineering for a Sangoma config template if you're rolling out more than a handful of phones outside a FreePBX context.
