We've used the Portech MV372 in the past (two-SIM version, but pretty sure
there's a single-SIM version as well). It seems to work okay, though the
web interface isn't the most polished out there.

You can buy them in the UK from Keison Technologies - www.voipon.co.uk.
They're nice people to deal with.

We have a few clients with Ericsson GSM gateways feeding into analogue
ports (on a Digium card - but same basic specs as your Sangoma). They
"mostly" work - but occasionally a call doesn't clear down properly and
stays up until the device is power cycled. You'll want to have an
AbsoluteTimeout() on such devices to prevent extraneous calls carrying on
indefinitely.
