External Presence Sharing
External Presence Sharing
note
This feature is supported only for version 70 and onwards.
You can share presence information between two tenants on the same PBX or across different PBX servers in separate locations. The PBX systems must be able to reach each other over the internet.
Example Scenario
In this example, we'll share the presence of extension 489 (John Wick) from a tenant on PBX02 with the extensions of a tenant on PBX01.
Configuration Steps
Step 1: Create an Inbound Subscription on PBX01
- Navigate to Tenant Settings → Trunks → Presence Sharing
- Add an inbound subscription for extension 489 on PBX01:
- Under Account, enter:
489 - Add a descriptive Name (e.g., "John Wick - PBX02")
- Set Visibility to:
*(asterisk for all extensions) - Click Save
- Under Account, enter:

- Copy the generated URL – you'll need this for the next step

Step 2: Create an Outbound Subscription on PBX02
- Navigate to Tenant Settings → Trunks → Presence Sharing
- Add an outbound subscription:
- Select the local extension (extension 489 in this case)
- Paste the URL copied from the inbound subscription on PBX01
- Click Save

Monitoring External Presence
