[Freeswitch-users] Disable Goodbye playback for a particular user

Hello FS users, I have some customers trying to utilize automatic redial feature with their pots lines. But when the analog phone listens for a "Goodbye" message instead of busy tone it can't determine that the line is busy and automatic redial fails. So the question is whether there is a way to disable or skip playback of a "GoodBye" message for a particular user or change "Goodbye" message for "User Busy". Thank you in advance.
