FAQs

Q: What does an FXO port do?
A: An FXO port connects the router to a PSTN central office line or an analog trunk on a PBX, allowing inbound/outbound calls via the analog line.

Q: Does an FXO port power phones?
A: No. FXO does not supply battery or ringing voltage; it terminates service from the telco or PBX. FXS ports power analog phones.

Q: Is T.38 fax supported on FXO?
A: T.38 fax relay may be supported depending on IOS, DSP availability, and peer capabilities; otherwise use G.711 pass-through.

Q: What licenses or IOS features are needed?
A: A voice-enabled IOS image is typically required for FXO call control, caller ID, and fax features.

Q: Can I mix FXO with FXS cards in the same router?
A: Yes, if slots and DSP resources are available, FXO and FXS modules can be used together.
