We have a customer with 300 ext in 10 groups. Group 1 - New car sales Group 2 - Used car sales Group 3 - Car Service Group 4 - Spares ... Group 10 - Customer Service If reception transfers a call to the Queue for Group 1, the music on hold for Group 1 Queue plays. Music on hold is a marketing message file informing customers about deals on new cars. If an extension in Group 1 transfers the call to another extension in Group 1, the system wide MOH plays. It would be ideal to have the following: Group 1 - Own MOH file, just like the queue for Group 1 If a caller to an extension in Group 1 is placed on hold, the caller should hear the Group 1 MOH file, not the system MOH file. Group 1 ext transfers call to Group 2 ext The caller should hear the MOH file for the Group 2 ext.
