Have system set up for incoming calls to main number to ring several phones at night and if not answered go to GD mailbox. Works fine, but someone in the ring group is asking for ability to forward their phone to an external number. Am wondering what will happen to ring group calls to that phone, will they be forwarded? There are no line appearances on the phone (all incoming calls come in on intercom}, so line redirect won't work. Can't find anything in docs specific to this problem. Any help would be appreciated.
