Services like Callcentric allow you to other Callcentric customers and open SIP networks for free. Plus they allow you to use any device, mobile, ATA, IP PBX, etc. And with Callcentric you can setup a completely free account and do this. However if you add any paid services there is a 911 fee of $1.50 per month. |
