RingCentral Integration

Connect a RingCentral number to Famulor by provisioning it as a Generic SIP IP Phone
RingCentral does not expose a true wholesale SIP trunk to retail customers, but it does support Generic SIP IP Phone provisioning — which is what Famulor uses to connect. You provision a virtual SIP endpoint in RingCentral, register it from Famulor with the credentials RingCentral generates, and route a DID to that endpoint.
Plan requirement: Generic SIP IP Phone provisioning is only available on RingCentral MVP / RingEX Standard or higher — not on entry-level plans. Confirm in the Service Web before starting.
Why this works as a “trunk”: Although RingCentral calls it an “IP phone”, the Generic SIP option exposes a username, password and SIP domain that any standards-compliant SIP UA can register against. Famulor’s LiveKit-backed SIP stack registers as that endpoint.

​
Step 1: Add a Generic SIP IP Phone in RingCentral

  1. Sign in to the RingCentral Service Web.
  2. Go to Phone System → Phones & Devices → User Phones.
  3. Click Add Device → Existing Phone → Other Phone, and choose Generic SIP/Other phone (manual provisioning).
  4. Assign a user (this is the user whose extension/DID will be answered by the AI).
  5. Save — RingCentral generates SIP credentials.
Older Service Web layouts list this under Phone System → Phones, Devices & Numbers → IP Phones / SIP. The wording shifts over time; the option you want is always “Generic SIP” or “Other Phone”.

​
Step 2: Pull the SIP credentials from RingCentral

In the new device’s settings, find the SIP Configuration / Setup details panel. You need: 
SIP Domain        e.g. sip.ringcentral.com   (or sipXX.ringcentral.com per region)
Outbound Proxy    e.g. sip.ringcentral.com:5060 (or 5096)
Authorization ID  long numeric ID
Username          long numeric ID (often same as Auth ID)
Password          generated by RingCentral
Use sip.ringcentral.com, not the regional sip12.ringcentral.com style hostname. The regional host is for RingCentral’s own desk phones — generic SIP clients should always hit the global gateway.

​
Step 3: Import the number into Famulor

  1. Open your Famulor dashboard and go to Phone Numbers → Integrate SIP trunk.
  2. Fill in: 
    Phone number:   The DID assigned to the user in RingCentral (E.164, e.g. +1 415 555 0123)
Username:       Authorization ID from step 2
Password:       Password from step 2
  3. Outbound settings: 
    SIP address:            sip.ringcentral.com
Outbound number format: International (with +)
  4. Authorization type: Username and password.
  5. Country: the country of the assigned DID.

​
Step 4: Wait for registration to propagate

RingCentral’s antiflood logic takes 1–2 minutes to register a brand-new SIP endpoint. If your first test call returns 403 or 404, wait two minutes and retry — repeated failed attempts during the propagation window can extend the lockout.

​
Step 5: Verify

  1. Assign the number to a Receive phone calls assistant. Call the DID — the AI should answer.
  2. Create a Make phone calls assistant with the same number and trigger an outbound test call.

​
Common issues

Almost always RingCentral antiflood. Wait 2 minutes, then retry. If credentials were copied with a stray space, RingCentral will lock the endpoint for a longer cooldown — re-paste carefully.
Make sure the DID is routed to the extension that owns the Generic SIP IP Phone, and disable any “simultaneous ring” rules on that extension that would also ring desk apps.
Force PCMU/PCMA codecs. Disable G.722 in the device settings — RingCentral’s media servers occasionally negotiate G.722 even when the SIP UA prefers G.711, which causes one-way audio when the upstream platform doesn’t support it.
