[VoIP] Decadic Savvy ATAs

[Mark Rudholm]

The new/latest Digum S101I ATA supports pulse and is readily available
for purchase here: http://store.digium.com/products.php?category_id=9
All Digium hardware supports pulse and they have no plans to discontinue
pulse support.  Note also that you are in control of what firmware gets
loaded onto your S101I, as it is loaded via Asterisk.

I don't have any vintage switchgear, all my rotary dial telephones are
connected via S101Is or other Digium hardware.
