Voicemail is not working on your iPhone and you don’t know what to do. It’s incredibly frustrating when voicemail won’t work, especially if you were expecting an important phone call from a friend or family member. In this article, I’ll show you what to do when your iPhone won’t play voicemails so you can fix the problem for good.
1. Open the Phone app — the app that you use to make phone calls and track your contacts — and tap "Voicemail" in the bottom-right corner.

Some wireless carriers give their subscribers the option to send voicemail directly without ringing the other party’s line. This generally is only available if both parties are on the same carrier, but when it’s available it’s super easy.
The importance of voicemail in the customer care sector has not diminished despite the arrival of newer web technologies. VoIP applications let the businesses use voicemail service with flexibility, as it is. The users need not rely on extension terminals when they use VoIP services. A strong internet connection is a prerequisite and the pre-configured phones can be used – both for calling /receiving calls and for automated custom greetings. IVR feature redirect callers to the right virtual extension where their needs can be addressed. This can be done anywhere through a web portal access and an internet connection.
