I had hear about Welltech (http://www.welltech.com/default.aspx) gateways but I don't have any experience with them.
Someone know ?, any experience...

Hello,
Samuel: We also have some GXW4104 gateways, in small production/testing environments; our caller id works fine and none of them has failed in over a year of being used. The thing that i dislike about the GXW series is that it has no support for early media.
Everyone: What FXO devices do you currently use / recommend?
2009/11/25 Chris Chen <chris.chen2004 at gmail.com>
You haven't really put it into production for more than one year. The issue with GXW4108 is that after some time, say a couple of months, either all FXO ports not working, or worse, some FXO ports not working, but after power recycling, they will come back to work for some time until on strike again at some time you have no control.
This had been reported for a couple of years without improvement. Go google search you will find out, this has happened to many GXW4108 users.

Thank you for those tips,
I do have some small setups using gxw4108 they work or, except CID
doesn't seem to work. I will try the channel bank route - just don't
know too much about the setup options or how you'd purchase the
correct config, eg. For 150 FXS channel bank, can I get a single PCI
card for that?
I may end up using the grandstream fxs gateways then use the T1
channel bank from sangoma,
Thank you all..
Lastly, I know asterisk now has an offical skype_ module, Is there
anything similar I could use?
