[BUG]-Configs with only Dialers will not properly subscribe for Dialer Feedback.

[jtalborough]

Describe the bug When a config only has dialers init with no faders the subscription for the dialers does not execute properly. No Feedback.

Work around is to add a fader config object.

Thank you @cdenig

Added the following to config and dialers send their subscriptions too

          "faderControlBlocks": {
            "Voip1Rx": {
                "enabled": true,
                "isMic": false,
                "hasLevel": false,
                "hasMute": true,
                "index1" : 1,
                "index2" : 0,
                "label": "VoIP 1 Rx Mute",
                "levelInstanceTag": "",
                "muteInstanceTag": "VoIPReceive1",
                "unmuteOnVolChange" : true,
                "incrementAmount" : "1.0",
                "permissions" : 0,
                "bridgeIndex" : 1
            }
          },
