I would be cautious regarding echo performance, as enhanced echo cancelling
software are now available on some telephony cards (HPEC, OSLEC, ...) and I
can't see at the moment (experience will tell) why Patton gateways would
perform any better or worse than telephony cards. I would be very curious to
read other testimonies on that.

On another topic, I would say those gateway are not so easy to configure :
- a web server is embeded but it is not documented anywhere and it's GUI is
far from natural,
- alternatively, you can edit a config file for which a huge doc is
available but, as this boxes are not specifically designed to work with
Asterisk, doc is not easy to understand (it took me 3 days to find how to
register a gateway to an Asterisk server).

Anyway, configuring ISDN ports is easy and the range of possibilities is
larger than with telephony cards :
- BRI/PRI, TE/NT, PtP/PtmP : every case is supported (BRI/NT/PtmP is not in
latest libpri, for instance)
- routing seems very powerful.


In the long run, I would preferably use telephony cards (or products)
manufactered by companies directly contributing to Asterisk source code
development (Digium, Xorcom, ...), and build telephony gateways with
Asterisk, those telephony cards and off-the-shelf components, but I'm not
sure conditions are met to do it now.

That's why I'm also using Patton gateways at the moment and I think it's
good to consider using them.

Hope this helps.
