MyPBX is missing one of important features that also other PBX's have as basic functionality. We need to have information of unanswered call in our e-mail.
This is basic functionality, just to get info when the call was made and from whoom. Advanced functionality that are present on some of PBX systems is click to dial back unanswered call, so you can call back - press on the button that comes with e-mail (as part of e-mail) and then phone rings that number back.
When somebody calls you in the office and you are not in the office, you don't get the info that somebody called you. When you have e-mail on you mobile, then you know (this is when person doesn't want to wait for the call to be transfered to mobile or call forwarding is not activated).
