[Asterisk-Users] Cisco ATA 186

[Iain Stevenson]

Search the list - there's a detailed answer on it.

I have two of the I1 version (at least that's what they say they are - 
ProductId: ATA186I1) and they work with UK spec phones.  All you need to 
watch for is that UK phones are three wire and US phones are 2 wire. 
Maplin sells an adapter to sort this out (Part no. VD36P).
