FAQs

Q: What use cases benefit from 132 FXS ports?
A: Large deployments of analog phones, patient room lines, elevator phones, door phones, fax machines, and modems in hospitality, healthcare, and campus sites.

Q: What are the 6 FXO ports used for?
A: They provide local PSTN trunk access for emergency calling or fallback when WAN connectivity is unavailable.

Q: Does it interoperate with third‑party SIP systems?
A: Yes. It supports standards-based SIP for broad interoperability.

Q: Can it maintain calling during WAN outages?
