Twilio with calls routed to the free call forwarding Twimlet. $1/number/month, plus $0.03/min. The free $30 credit will keep you going for a long time.

I'd go with Twilio too ... only issue is you need to have upgraded your account to port a number:

But since credit's don't expire, and you can always find another use for Twilio in the future it is a good bet.

You can upgrade without paying until your balance runs low. Just set up auto-renew and you can buy a number.

I thought Twilio is for web sites that want to integrate voice services. Can I use it only for forwarding a number?

[apowell]

Definitely. In Twilio, you assign each phone number a URL that handles inbound calls. Create the Twimlet forwarding URL and paste it into Twilio as the "Voice Request URL". Once you do that, your calls will be forwarded.

You can provision a throwaway number on a trial account if you want to test it for free.

Twilio looks pretty cool. I had only heard about it but this looks very good.

I have created a URL in the format http://twimlets.com/forward?PhoneNumber=<my number>& and entered it into my app under Voice/request URL. Option is "Post". But when I call my new number (I have created a new number with another account) the call doesn't get forwarded.

Am I missing something?

Never mind. Got it. I am impressed! I could have used this some years ago for an app I was working on.
