Ring-Groups
About
A ring group acts like any other Asterisk extension number except it rings a collection of Asterisk extensions which you specify. If you dial a ring group number, it will ring all of the Asterisk extensions associated with that ring group.

in the Before State line. Select Action: Forward, Forward to: External number, enter the number and click Change.
Device is now ready to be assigned to a Ring group.
Ring Group Device limit
There is a limit of how many Devices can be added to Ring Group. There is no exact number of how many Devices can be added to Ring Group because this limit depends on Device extension length. You will be able to add more Devices with shorter extensions to Ring Group.
Once limit is reached, you will see error message Ring Group is full, Device limit reached.
This limit comes from Asterisk not being able to read more than 512 characters from dial string.
