[Asterisk-Users] FXO interfaces used in UK?

[David Gurr]

What FXO interface methods are folks using successfully in the UK?

I'm looking for good, known-to-work solutions for commercial use for two
PSTN trunks on an Asterisk box. Here's the options I have, as I see it:

i)	Two Digium X100Ps. Pro - cheap (c. £120), CE approved. Con - UK line
impedance mismatch, with resulting echo problems, plus needs two PCI slots.

ii)	Digium TDM400P with two FXO modules. Pro - still fairly cheap (c. £200),
and can be set to UK line impedance, plus only uses one PCI slot. Con - Not
yet CE approved.

iii)	Voicetronix Openline 4. Pro - reasonable price (c. £310), CE approved,
only uses 1 PCI slot. Con - UK line impedance mismatch.

iv)	FXO gateway:
	- Multitech MVP210. Pro - UK line impedance, no PCI slot needed, good local
technical support, CE approved. Con - expensive (£590 list)
	- Mediatrix 1204. Pro - As above, plus not so expensive (£389 from
Telappliant). Con - can't get to see manuals to check functionality until
you buy it

I'm leaning towards either the TDM400P with 2xFXO, or the Mediatrix 1204,
though because of the cons I'd like to hear from folks that have
successfully used these in this type of configuration in the UK before I
shell out for them!
