I have purchased an Cisco ATA186 for 99.99 USD (Vonage Digital Voice package) from Amazon and factory resetted the device. It works perfect with http://www.iconnecthere.com I can recommend this setting to everyone interested to use a standard analogue phone for Voice over IP. The voice quality and ease of use is perfect. I have only 62k upload bandwith and a network latency of 300ms to the US. Iconnecthere has a setup description and offers free 0800 calls to the US. This could be interesting for anyone living in a monopoly telco country with no access to cheap phone rates with prepaid cards from their own country. Via the US good rates are available. iconnecthere does have low but not very low rates for international calls.
