Asterisk voicemail implementation provides integrators with option to replace proprietary existing voicemail systems with Asterisk voicemail at a merely symbolic cost. The service can be applied as a basic stand-alone utility or can operate a front end of an Unified Messaging system, holding messages by IMAP or ODBC. Creating the Asterisk voicemail server is simple and just a fraction of dial plan scripting is being needed.
Citel PBXgateways are installed at the central PBX location, and EXTenders are deployed at branch offices, call centers, or at home offices over managed IP connections, DSL, cable, or analog circuits
