asterisk users - Jul 2003 - experience with multi-port SIP/FXS gateways?

I'm proposing an asterisk configuration and considering the use of
multiport SIP/FXS gateways (instead of T1 cards and channel banks).
I'm looking for products similar in function to the Cisco ATA-186,
but with more ports.

I've seen the manufacturer's web pages for the Audiocodes MediaPack
(http://www.audiocodes.com/) and the Mediatrix (http://www.mediatrix.com/)
access devices.

Does anyone have any experiences to share with these or similar
devices, or opinions on the relative merits of gateways vs channel
banks?

Thanks very much!

I am using the audiocodes MP-108 FXO as a SIP gateway to the pstn, 
it works fine, and asterisk can receive and make calls thru it, caller 
id is also working ok. As for now the only remaining issue that i have 
pending is with conferences, the channels of the lines that get into a 
conference doesn't get freed in the gateway nor asterisk after hangin 
up,  i'm going to try a 'exten =>
confexten,somepriority,Hangup()' after
the Meetme command. This seems to be an issue with SIP, because i don't 
have that problem with my X100P FXO card.

Hi, we have a 4port device using the silabs 3050.. great as an fxs
module.
One application works via a PHP scripted java softswitch.
So far asterisk has not compiled for me.. I guess they want u to buy a
card and then give a version that builds :)
Anyway..we will likely sell the system with source code so other
programs like asterisk or SIP/H323 can easily use the devices.

At this point, the device works as a call logging solution..and call
center with a soft pc-client using g726/729/ulaw dll's to keep java up
to speed
As an applet scripted client that can popup on inbound calls etc.

Perhaps there is  need for an OPEN sdk for fxs CTI projects.. we have 3
modules.. fxs,fxo and headset.
