You could try DIDLogic (http://www.didlogic.com/). I am a happy customer, as I can:

- Rent an inbound number for each of the countries that are important to me

- Set up multiple SIP accounts to use for outbound calls (much lower per minute rates than Skype or Rebtel)

- Set up one or more of those SIP accounts to ring when I get an incoming call, even doing it in sequence if I want

- Set the caller ID on outbound calls to whatever I want (e.g. my normal mobile number, or one of my rented incoming numbers) on a per-SIP-account basis

I use GroundWire on iOS as my SIP client. There are cheaper options. GroundWire is great, in part because they use Push notifications, but this requires you to trust their server with your SIP credentials.

I am cofounder of http://aircall.io I created it because I didn’t find an easy phone solution with a great UX for my previous startup.

Feel free to register to our private beta, we still have several hundred active users. I will be happy to show you aircall and discuss with you about your needs

We use http://www.Tropo.com/ scripts that forward to our cell phone #s. Blog post: http://socialhealthinsights.com/2013/08/checkqm-support-powe...

Also check out http://www.ringio.com/ for a more robust turn-key-ish solution (met the founder but have never used them)

You might try our software https://calltrackingmetrics.com/ - we provide a call queue feature that can route to all 10 of your employee's. Our focus is on analytics and reporting for your marketing, with integration into google analytics/adwords - but the call log is pretty useful for keeping track of customer calls too.

Hi,

You may want to check out my startup Callbase. http://callbase.co.

I'd also love to learn about your particular use case if you are ok with it.

My email is in my profile.

I work for http://www.voclarion.com. Might be worth a look, though we offer a host of features you might not need.

http://nextiva.com does this well. We use it, excellent customer service, very competitive prices.

We're using http://aircall.io, it works well and provides a clean administration interface.

Looks nice, although it's in beta. How much is it compared to say, Grasshopper.com?

Aircall is a bit different from GH. Our pricing is not final yet but if you're a lone user only receiving very few calls, GH will be cheaper. If you're a team of a few people or if you receive or make a decent amount of calls/week, Aircall should be >20% cheaper at least. if you're interested, drop me a mail at olivier@aircall.io so I can make you jump our waiting list (once you've tried the product I'll be happy to share with you our detailed pricing ideas - even if not final)

Very hapy with the combination of: localphone (for credits and numbers) with pbxes (hosted asterix)
