US 500 Series FXO/FXS

[letkris44]

Hello all. I just need to clarify/ask a question. From my discussions with Cisco tech support, the maximum number of FXO and FXS ports I can have on a UC 500 series is 8 of each, using a VIC card for 4 more FXO and a SPA8800 for 4 more FXS.

Does anyone know of anyway to increase this? I have a client who needs to run with 12 FXO and 12 FXS to make a functioning system.

Does anyone have any other solutions I can deliver? (And please do not go into BRI or SIP; it's not going to happen.)

Thanks all.

Hello Kris,

If you are using UC560-FXO and add two additional FXO VICs - VIC2-4FXO you will have a total of 12 FXO ports.

Then add SPA8000 will give you additional 8 FXS ports - total 12.

This is how you add SPA8000 to the UC.

For FXS also you may use ATA186.

HTH,

Alex
