I'm wondering if it's possible to ring the android client separate than the desk phone based on some criteria. i have a ring group setup that rings a few extensions at the same time on inbound external calls. some if these extensions are setup with desk phone and mobile clients. some people dont want their mobile clients to ring on inbound external calls, they only want both mobile client and desk ohone to ring on internal calls and desk only on inbound external calls. is this possible?
