Preventing simultaneous calls to same number


Is there any way we can prevent a call trying to connect if there’s already a connection to the same number? I have an iOS app, and sometimes it will call same number twice at the same time, so I would like to make Asterisk drop any attempt to a number already started making a connection to…

Appreciate any help on this, have been searching a lot, but can’t find this feature…


Put the call in a particular group using GROUP function and use GROUP_COUNT function to decide if there are multiple calls on the same number.
