We need a simple Nexmo integration based on PHP that will do the following:
1) simple html - with number to call, and "call" button.
2) click will call SIP phone first and once answered will call the number.
3) call will be recorded and a saved to file \ get a url to file on nexmo.
4) instructions to connect any free android SIP phone application to your choice to make test the module.
budget it really low - so better it you have Nexmo integration experience.
more work to come once completed well.
