Voice shout messages are unidirectional calls (microcalls) which transmit your voice message to any telephone receiver, which is automatically played to the receiver. Shout messages are as urgent as a phone call but as laid back as a standard voice message. Voice shouts are low cost messages which can effectively be transmitted between continents at a very low price.
Send your voice messages as microcalls; your buddy will receive a call, hear your message, and will even be able to reply to it in real time!
Q: Why should I send shout messages instead of just sending an SMS or just making a call?
A: When you send a shout you can avoid staying on the line and waiting for someone to pick up the phone on the other end. This can be very handy when you are, for example, driving a car or in any other situation where time and delivery are critical.
