Whenever we need to make a group of extensions ring when a call comes in, we set the Ring Groups module. This feature is very useful when we have a group of support technicians or sales representatives and we do not want to lose or let a call go to voicemail.
The steps to setup a ring group are as follows:
Create a ring group in the PBX | Ring-Groups menu; this means, add an extension that will point to the ring group.
Enter a description for this ring group.
Set Ring Strategy.
Set the maximum Ring Time.
Enter the list of extensions to ring. You may leave the rest of the options with their default values.
Enter a destination in case no extension answers any incoming call to the ring group.
