Hello all,
I have a Cisco 7940 IP phone with SIP protocol. I was told that I could use ipkall, google voice, and antisip.com to get Free service. I followed my friends directions and didn't work. Does anyone know how I can do this successfully? I'm wanting to use the phone as a business phone. I would like to be able to make calls as well as receive calls. Free is great but willing to pay a reasonable monthly fee for service that can simplify the process. Any help would be appreciated!
