Title: Connecting PSTN into CUCM
Post by: Dieselboy on May 22, 2016, 11:02:17 PM
Has anyone used a FXO gateway on CUCM like a Linksys SPA or similar? Any recommendations for cheap and dirty but does the job for linking a PSTN line into CUCM?

You'd need FXS to connect to the PSTN, FXO is for phones, faxes, etc.

Opposite way round :)

FX"S" = "Station" and "Station" = telephone endpoint.

FX"O" = "Office"

I just don't want to buy a line card, DSP and license which is totaling up to almost $2k.

There's small "gateways" which are <$100 with FXO ports. I just don't know if it will work, and if it does work how reliable it will be. Will it need rebooting every week - probably.

Haha I was just testing you... :-[

I've never used anything other than a gateway with a VWIC. I don't do much with voice anymore, a blessing and a curse.

Its a blessing :)

Jokes aside, a few years ago we were looking at SIP compliant ATAs/ analog VGs and Grandstream kept coming up as a cheap 3rd party SIP compliant option. As usual with integrating 3rd parties into CUCM, check the exact functionality
