Hello there, we want to build a software to ring numbers and then they should see it as a "Missed Call", and they will then call back.
I am not sure 100% if this works, so that's why we need one expert on VOIP/Call Center area. Please only write if you want to work with us in the long term, so we are searching someone to give us tips and also to advise us in this direction.
For us is very important to have a really good partnership, it is not a matter of money, for us is important to have long term connection.
I am really happy to see your offers.
