What is the difference between a short message and a voice message?Submitted by Admin on Tue, 08/11/2015 - 10:33am
The short message is an instant SIP message, the contents are sent via text format. If you do not receive the message, it will not be saved by the server or forwarded again. A voice message consists of RTP packets and can be saved on the server. When the caller cannot reach the callee, a connection is established with the server and the voice message is recorded. The server will then notify the callee that there is a voice message waiting and a connection will be established to retrieve the message.
