[asterisk-biz] UK GSM gateway with Asterisk?

[Dan Journo]

Can anybody recommend a single line GSM gateway that is compatible
with Asterisk and available in the UK?
I have a spare FXO port on my Sangoma A200 card if it will interface
with this? Or do they usually present as an extension/FXS?

Check out this page. They have a stack of them. Voipon have quite good delivery times and pricing.

Never used a GSM gateway though, so cant recommend one.
