Ready To Get Started With Asterisk? Asterisk is a free and open source framework for building communications applications and is sponsored by Sangoma. Welcome to Asterisk Watch the Video Watch AstriCon Live The 2020 virtual event, AstriCon (Plan 9), will be held on October 21st – October 22nd. We kick off AstriCon with Track Espanol Open Source Communications Software Asterisk. In our example, the extension 100 will redirect an unanswered call to the voicemail after 5 seconds. In our example, the extension 200 does not have voicemail. In our example, if any extension dial 500 it will be sent to the Voicemail menu. Delete the content of the voicemail.conf configuration file.
