[cisco-voip] FXS or FXO?

[Norton, Mike]

The Cisco FXO port normally acts like a station and expects to see an office. The Avaya station port acts like an office and expects to see a station.

So to be clear, in my scenario... The CISCO port would be "emulating" an analog handset to the Avaya.

I guess that's where my confusion comes in; in that a CISCO FXO port is normally expecting to see a CO, not a station.

The Avaya station port will be expecting to see an analog handset, so my CISCO side needs to be able to act like that.

So the consensus is FXO port on the CISCO side?

I guess it depends on what you define "routing" as. Yes you can send ring voltage out an FXS port, but all that tells the other side is to ring because there's a call. It doesn't tell it where to send the call so I wouldn't classify sending ring voltage to be routing a call.

You can send calls in both directions (just as you can send and receive calls on your land line at home, which is essentially an FXO).

The FXS port can route calls, at least in the manner that it provides dialtone and receives digits.
The FXO port is just told to ring but can send digits when making an outbound call.

Um... no. Like ports do not connect. One sides needs to provide battery and dialtone, and one sides needs to accept battery and dialtone. Always office ports to station ports.

In this scenario, since the Avaya is provide the station port, you need an office port on the Cisco.

If what you're trying to do is this:

avaya:FXS <-----> FX?:Cisco

I don't think you can.

an FXS port is just that, a station port.

I believe you have to do this:

avaya:FXO <-----> FXO:Cisco

There _may_ be FXS/FXO converters out there from the likes of Viking, etc. but I think FXO to FXO is what you want/need.

Looking for a quick answer on something.

For a specific scenario, I need to route calls from Cisco to an analog "station port" on one of my Avaya's.

Question is; do I need an FXO or an FXS in my router to accomplish this?
