[VoIP] Decadic Savvy ATAs

Mon Jan 14 20:16:24 CST 2008

I've had very good luck buying channel banks for less than $50 bucks recently.

But where have all the 3810's gone?

For up-to 6 ports, use a Cisco MC-3810 with 6 FXS ports.

They can be had on eBay for about the price of 2 or 3 iaxy's.

In theory, you could attach a channel bank (about $100 on eBay) to the

T1 port and have a total of 30 ports.
