What the “custom contexts” add-ons do, is to connect your custom dial plan with VitalPBX GUI.
for example, you may create a file named “extensions__60-1-custom.conf” under “/etc/asterisk/ombutel” path, and add the following dial-plan:
[custom-dialplan]
exten => s,1,NoOP(Dummy DialPlan)
same => n,Playback(vm-welcome)
same => n,Hangup()
So, how you may execute this custom context on VitalPBX?
Easy, using the custom contexts add-on. With the custom contexts add-on, you may use your custom contexts as VitalPBX destinations, also, in the custom add-ons, you may configure a destination that you may use to transfer the call to another VitalPBX context after executing the custom context.
