- To enable onetouch voicemail (i.e., press the voice mail button and have it connect automatically) - go to the endpoint manager, go to advanced, basefile edit and select the template you created for the given model of phone (i.e., vvx410.) Click "SIP-interop.cfg." Look for a line stating:
oneTouchVoiceMail 0
And set it to 0.
Now, go back to "Extension Mapping" - select your extension and select "rebuild config." After this, reboot your phone.
