Story behind Pindo

Pindo started with our need to use our current voip solution on mobile phones. We just did not want to show our mobile phone number when calling customers or even worse and hide our caller-id. We wanted to present the same number that we use in our office.

We tried every possible voip app but the conclusion remained the same. It sometimes worked and sometimes not. For our business needs this was just not acceptable. We needed something stable. We noticed that voip calls were using up to 3 times more battery than a normal call or the smartphones were constantly switching between Wifi, 3G, 4G, or no data at all and the situation is even worse when moving or driving.

Our idea was to transform a voip call into something that is proven. So instead of doing a voip call we make a normal mobile call but not to the destination number but to a fixed line number attached to one of our servers. Some might argue that data is cheaper but it really depends which mobile contract you have. National flatrates or plans with a big amount of fixed line minutes are available for any budget.

Technically we combined the idea of a normal mobile call with a very little data packet sent before the call starts. The single data packet has all the information our server needs to forward the mobile call to the voip provider. We can now present our business number and as a positive side affect we benefit from low international call rates.

We developed the idea and finally filed for a patent. The information is now public and can be found here:

I prefer to keep my mobile number private, but I can call from my smartphone and show my office number.

Finally when customers call me back , they reach our office and get a professional phone reception.

When the discussion becomes important, I just push 99 to record the call and can listen to it later when I have more time.

I save lots of money when calling my family, voip providers offer the best international call rates.

Frequently Asked Questions

I am a voip provider, can you include me in your predefined list of voip providers?

Please contact us at This should not be a problem.

Can you recommend a voip service?

Pindo tries to be neutral on this point. Any decent voip provider supporting the SIP protocol should work. But Pindo works as well with SIP pbx'es like Asterisk, 3cx, Cisco, Avaya, Innovaphone....

What about roaming?

Roaming is complex and we hope that the European Union will at least solve it in Europe very soon. If you stay for a longer time in a different country we recommend to buy a prepaid card or a short term contract at a mobile provider. After all, with Pindo it does not matter which SIM card you have, as your voip service provider will show the caller-id of your voip account.
