Device Directory
The directory lists the device options available for accessing SIP based VoIP applications and content. Moore's Law like forces arising from the competition between the large number of companies producing SIP phones has produced a dramatic reduction in the cost of the devices. VoIP-Info lists hundreds of companies making softphones a hardphones. A few VoIP focused device distributors have emerged like VoIPSupply, Telephony Depot, and IP Phone Warehouse. ATA's represent the absolute cheapest path to SIP access, but the directory omits the devices as too closely linked to the old telephone model. The emerging competition between cell phone operating systems (iPhone, Android, LiMO, Symbian, Windows Mobile, etc) promises to provide very interesting platforms for SIP enablement.

Escaping telephony constraints
There remains a remarkable lack of creativity in available SIP devices. The presently available devices incorporate all the performance and user interface limitations of traditional telephones even though SIP erases many of the old constraints. This does not represent a significant surprise given the dominant demand for the devices comes in the context of telephone network interconnection. The SIPtoSIP directory seeks to create demand for SIP only devices toward unleashing the potential of communication absent telephone network constraints.
