Sangoma phone desktop BLF?

If i go into the UCP and edit/set my favorites for my various feature codes, with the “*” in front of them, they import into the Sangoma Phone softphone for windows on reload. But if I try to add the number through the softphone app itself, it only acepts numerical values. It does not accept a “+” either which could be an issue for e.164 dialing? I still don’t get blf status for the feature codes though.

Through the mobile sangoma Talk softphone on android, i can use non-numeric characters and I get a blf status for my features codes.

So unless i’m missing something, it looks like the desktop client is lacking in some functionality.
