[Asterisk-Users] Options for 3+ FXO ports

The Mediatrix 1204 FXO gateway sort of works with asterisk in the US, but
have had a few issues with CallerID being recognized when the four pstn
lines have different ring cadence (at least I believe its a cadence issue).

Other then that, there seems to be a significant market opportunity for
anyone that can produce a reliable 4-port device.

A goggle search for channel banks turned up www.nextag.com with samples such
as this:
Adtran TA750 Chassis w/psu ac adapter $900
Adtran Quad FXO card: $230
Adtran TA750 w/12 FXS ports: $1250
Adtran TA750 w/FT1, 20 FXS: $1900

However, I don't consider those prices cost effective for four ports after
adding in the digium T1 card, etc.

I'm interested in a 4-port as well if anyone knows of something.
