hallo I need to kown how to configure grouping call.thank
We need to know what a “grouping call” is!
I agree with David that your question isn’t that clear to me either.
But i 'll take a guess:
If you want that multiple phones ring you could do
Dial(SIP/Phone1&SIP/Phone2&SIP/Phone3)
or you could create a queue and set the strategy to ringall (ringall is default as well)
