Hi All, Is there any know issues with Cisco504G + BLF and Firmware Version 7.4.7 I configure the Line4 key to monitor the Extension 201. The following configuration I used. Line 4 Extenion : Disabled Shared Call Appearance: Shared Extended Function : fnc=blf+sd+cp;sub=201@mydomain.com;nme=201 Short Name: Ext 201 When Ext 201 on the Phone BLF works then after few second the BLF key stop working and the LED lights off. But Ext 201 still on the phone. Any help is appreciated. Thanks Lloyd
