At a glance
| Direction | Inbound: Zadarma forwards calls to Kollie |
| How | Call forwarding on a PBX extension, set to External server (SIP URI) |
| When the agent answers | Always, or only when nobody picks up (your choice) |
Before you start
- An active Zadarma virtual number and a configured Zadarma Cloud PBX.
- The internal PBX extension that your virtual number rings on.
Setup steps
- Add your number in Kollie
- Go to My Numbers → Add Your Number.
- Select the country and enter your Zadarma virtual number. Then click Add.
- Attach the number to the agent that should answer. See Step 1 of the overview.
- Open the extension's forwarding
- In Zadarma, go to My PBX → Extensions and select the extension that your virtual number rings on.
- Next to Call forwarding and voicemail, click Set up or Enable.
- Choose when the agent answers
| Option | What happens |
|---|---|
| Always | Every call goes straight to the Kollie agent. |
| No answer | Your extension rings first. The agent takes over only if nobody picks up or the extension is unreachable. |
- Forward to Kollie
- Under Forward to, choose External server (SIP URI).
- Enter your virtual number in E.164 format, then
@, then Kollie's SIP domain:
| ✅ Correct | ❌ Wrong |
|---|---|
+49301234567@luvjtjd3aor.sip.livekit.cloud | 0301234567@luvjtjd3aor.sip.livekit.cloud |
+49301234567@sip:luvjtjd3aor.sip.livekit.cloud |
- Click Save.
Test checklist
- Call your Zadarma virtual number from another phone. If you chose No answer, let the extension ring out without picking up.
- Zadarma forwards the call and the attached agent answers.
- The caller's real number appears in Agent Calls History.
- Audio works in both directions.
Troubleshooting
| Symptom | What to check |
|---|---|
| Calls don't reach Kollie | Forwarding is enabled on the right extension · External server (SIP URI) is selected · the number before @ is in E.164 with + and matches your number card · the domain has no sip: · the number card shows an agent |
| The agent answers before your team can | Switch forwarding from Always to No answer. |
| The agent never takes over when nobody answers | No answer is active · the extension actually rings · Zadarma voicemail isn't picking up first (a voicemail counts as answered, so the call is never forwarded) · the full address is entered |
