with X100P cards as it doesn't seem to be practical to have more than

3


X100P cards at the time (IRQs is the main problem I think). At four

FXO


ports, I can't quite justify something like a full T1 on a monthly

basis.


But, since I've never ordered one, I'm thinking that it's a "all or

nothing"


deal (i.e.: I can't order a T1 and pay for only 4 voice channels).

It would


seem that the best I can do is a 3x8 configuration according to the
information on this page


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.

See: http://www.welltech.com.tw/


No yet tested, but waiting my first samples next week. Have callerid
and reversal polarity detection!. Prices seems to be half of Mediatrix.

I have been eagerly awaiting word on these devices! They would not give me one on evaluation, and charge a 20% restocking so I have not tried them myself. Please post your findings :-)

I will
