Intercom and BLF

[eric@salemcomputer.com]

Looking for anyone with advice on how I can have DSS Keys that monitor BLF status but make an intercom call when pressed. Using T48S with Yeastar S Series. I can get intercom OR BLF to work, but when intercom works BLF does not and when BLF works the calls ring instead of intercom. I was thinking I might be able to use a dial plan but can't seem to get that working either.
