Free local virtual phone number

I am looking for free local virtual phone number for long time, finally got this one: freephoneline.ca, it's best service and real free.

There are few reasons we need this virtual number.

1) call forwarding

freephoneline can forward to 3 phone numbers, so we can hidden them in one public number, they will ring one by one, if all of them not available then will go to voicemil box.

From receiver, the display number is still caller number, not freephoneline number.

2) voicemail

It's nice to choice to copy all voicemail to your email box, so you always can check the voice message.

3) SIP support

you can buy ATA+SIP account $99 or SIP account $50 as once investment, then you will have VoIP desktop phone at home or setup smartphone as SIP phone, it's unlimited call within Canada without monthly payment.
