Magicjack is working to have Skyp-like service for calls without the jack as well as a device for the enterprise market.

The company has several patents pending, including one for a wireless MagicJack that lets users with wireless networks have access to the service whether their computer is on or off. Rather than have them try to plug it into a modem and figure out where the Ethernet cables go, they can just plug it into the wall and it self-configures.

MagicJack work by plugging the device into a computer’s USB port. Nagicjack features an RJ11 jack for connecting a traditional home phone. The service supports caller ID, voicemail, voicemail-to-email and call forwarding.

The device works when the computer is on and will forward inbound calls to a cellphone if the computer is off.

The company’s strategy is super-low-cost calling. After the first year is up, it costs $20 for a full year of nationwide, all-you-can-dial calling.

Magicjack originally was designed for business travelers. However, with the current economic climate, people are desperate to get rid of their landline phone. The most MagicJacks have been sold in Florida and California, respectively, where economic times are tough.

Magicjack have also been used by retirees who are looking to minimize fixed expenses.

The company next strategy is to sell Magicjack as a hardware device and not a service that provides a retailer with recurring revenue when a calling plan is activated.
