asterisk users - Feb 2008 - Interoperability between TE412P and Eurotech PRI E1 GSM & CDMA Gateway

Hi,

I am about to purchase an Eurotech PRI E1 GSM & CDMA Gateway to operate 
with my Asterisk's TE412P interface.

Anyone here has any experience of having this combination? Any success 
or failure stories would be greatly appreciated.

Thanks in advance.
