As mentioned earlier, FIBERME devices are fully compatible with any third‑party device that follows the standard SIP protocol, allowing flexible integration in mixed environments.

For example:

• You can use a FIBERME IP PBX and connect it to a third‑party VoIP or PSTN gateway.

• You can deploy a third‑party IP PBX and connect it with a FIBERME gateway for trunking or legacy integration.

• You can register FIBERME IP phones to a third‑party IP PBX platform.

• You can use a FIBERME IP PBX together with third‑party IP phones as SIP endpoints.

This SIP‑based interoperability gives you the freedom to combine FIBERME with existing infrastructure and select the best devices for each customer scenario.
