How to set different callerIDs to ender auto-attendant?
1. Your OBi110 is able to detect incoming caller IDs.
2. Use the following way to set up your OBi1xx.
Set:
Voice Services -> SP2 Service -> X_InboundCallRoute : {(Mcot):aa},{ph}
User Settings -> User Defined Digit Maps -> User Defined Digit MapX
Label: cot
DigitMap: (CallerID|CallerID|CallerID|CallerID)
Replace 'CallerID' above with the actual CallerID's you wish to access the Auto Attendant, making sure they're exactly as shown in the Call History when that person calls you.
