When a call arrives on a DISA line, an OGM is played.At the same time, the PBX begins fax signal detection. If a fax signal is detected, the PBX recognizes thatthe call is a fax call, and transfers the call to the fax destination assigned to that OGM through systemprogramming.This allows a single trunk to be used seamlessly for both voice and fax calls, with only voice calls arriving atuser extensions.ConditionsConditions NoteThe PBX can detect only a fax tone from an analog trunk.The following numbers cannot be set as FAX Destination:• Trunk Line / Trunk Group, Idle Line Access (Refer to 2.1.1 FeatureNumber Lists for User)• DISA (Refer to 3.1.4 DISA (Direct Inward System Access))• Meet Me (Refer to 3.9.2 Meet-me conference)• Doorphone (Refer to 3.11.1 Doorphone Call)• Built-in VM (Refer to 5 Voice Mail Features)This feature is only effective for calls arriving on DISA lines.It is possible to register FAX destinations for each OGM.
