[asterisk-users] ATA for large networks

[Vieri]

Hi,

I would like to know if someone can suggest a multi-port ATA worth buying (at least 8 ports).

I have around 380 analog phones to convert to SIP extensions. So I need quite a few ATAs but they need to be "enterprise-grade", ie. they need to be reliable and stable.

I bought and have been using 11 Grandstream GXW4008 (8-port FXS ATA) in a production environment and have been experiencing stability and quality issues which are not acceptable in a large company.

I chose Grandstream because:

- it was a cheap way to start
- I thought their products were stable and reliable because I had already heard their brand name

So since my experience with 11 Grandstream GXW4008 has been overall negative (I need to reboot the devices too often!), I'd like to know if someone could help me decide what brand/model to buy.

I would also need to find these products in Europe (or at least deliverable there).

I've been considering a few products but I don't know if they are reliable:

TopGate TG8048 (48 FXS)
Soundwin S2400 (24 FXS)

In other words, I'd really appreciate feedback from voip administrators (not from resellers) who have had experience testing their devices and are happy with them.

Thanks,

Vieri
