I've a CME installed and working properly except for one thing. I've a hunt group configured with three members: two IP phones and and analog phone connected to an ATA186. The hunt group is configured as sequential and the last member is the analog phone. The incoming call enters the system and the first IP phone rings, after the timeout the second IP phone rings, and after the timeout the analog phone starts ringing. The problem is that the calling user starts hearing a fax tone instead of a ring when the analog phone starts ringing.
Does anyone know how to solve it?
