On the other hand sending voicemails or voice messages has some advantages over texting. Its cheaper and easier to send over especially if you broadcast voice messages to several people. For example, sending a voice message using Onesuite cost only 2.5 cents but sending sms usually cost around 10 cents for prepaid mobile plans.

What I'm trying to say is, voice mail isn't dead yet. It's here to stay for a few more years.
