IP phones

IP phone is an excellent solution for residential user or small office. You need high speed internet and connect this device to the cable/ADSL modem or you can use a standard networking equipment like a hub or router.

If you don’t have high speed internet, Telcan will provide you a dial up IP phone. This device is preconfigured with your ISP’s account information, and prior to make a call, the dial up IP phone will connect automatically to internet and will allow you to make a long distance call through our platform, avoiding your expensive local telephone company.
