VoLAN and WiFi Can create some exciting possibilities

Recently I had the opportunity to devise a sysyem for VoLAN (Voice over LAN) to offer a very unique solution.

The details of the project can be found at:

The project employed a unique device from Cyberdata which is a doorbell intercom. The wireless router shown is an over-simplification of the extensive Wireless Network that was already on site. Clearly the applications for SIP are growing when we begin to see devices available that have such limited, although useful applications such as the CyberData Intercom. What impressed me more however was the QuickPhones WiFI Handset , specifically it's Peer to Peer mode.

Part of the reason why this was such a good solution was the existing WiFi infrastructure that gave us better coverage than any long range cordless phone would have.

Since these devices were not relying on a server, we used P2P mode. The QuickPhones offers a P2P mode that allows IP address dialing via it's Phone book feature. This allowed us to set up multiple destinations instead of a "hotline" from the WiFi phone. This gave us the unexpected but much appreciated possibility of having more than one destination accessible from the WiFi handset. With a system like this one can easily establish intercom and possible PBX like functionality with no server, even with the functionality of PSTN lines via a device like an SPA 3102.

In the coming months I hope to have more time to explore such possibilities, and if any readers have any comments on the P2P functionality of the Quickphones , I would like to hear comments.
