Some SIM cards are not preset with the VoiceMail number at the factory, but the operator requires that the preset VM number be read from the mobile phone according to PLMN. This section describes how to preset VM number in xml format and how to allow users to modify and remember their choices. The priority of VM number is: SIM card reading> User Settings> xml preset. When you modify the voice mail number, the SIM card is preferentially stored. If the
Some SIM cards do not have a preset voicemail number at the factory, but the operator also requires the ability to adaptively read the preset VM number from the phone according to PLMN. This article describes how to preset VM number in XML, and how to allow users to modify and remember the user's choices. VM number uses a priority of: SIM card read > user settings >xml preset. When the user modifies voice mail number, the SIM card is first stored. If

Example
Exten => 123,1, answer
Exten => 123,2, playback (TT-weasels)
Exten => 123,3, voicemail (44)
Exten => 123,4, hangup
This is the definition of a single extension named "123. However, when a call is scheduled to extension 123, asterisk will answer the call by itself, play a sound
With the decrease in the cost of using VoIP, family and individual users are receiving more and more requests for using Vonage (or other similar products). As VoIP Communication continues to grow in the area of home calls, in addition, open source code projects are becoming more and more powerful. Based on this background and environment, Asterisk is a new product that can replace traditional PBX and is suitable for small and medium-sized companies.Th

Common storage mechanisms include CSV files, relational databases (such as PostgreSQL). Usually each call generates a call log that includes the caller, the call, the length of the call, and so on.The CDR module
Asterisk is a fully-software PBX system. It can run on Linux, BSD, Windows (simulated), and OS X. It provides all the features you want from the PBX, and is more than the PBX. Asterisk supports four types of VoIP protocols. By using relatively inexpensive hardware, it can interconnect with almost all standard-based telephone devices.

The asterisk core handles these items internally:
PBX switching-The essence of communication, of course, is a private branch exchange switching system, connecting calltogether between varous users and automatic tasks. The switching core transparently connects callers arriving on various hardware and software interfaces.
Application launcher-Launches applications which perform services for uses, such as voicemail
