A call forwarding group is a place where you add your number/s or VoIP member/s who are available to answer a call.
All numbers or voip members in a call group will ring at the same time, and the first to answer the call will receive it.
Call forwarding groups cost just £1.50 per month, and you can add additional call groups at anytime, perfect if you want to stagger the call flow.. Ie. Ring one group first, if no answer ring a different group.
Additional call groups are also used really well when using an IVR menu so that different phones are called depending on the option selected by the caller eg. Press 1 for sales rings only the Sales group
