LG G5 / LG G4 unable to setup wifi calling

Hello all,

I am having some trouble trying to get Wifi calling on my LG G5 and my LG G4 (2nd line).

When I try to set it up, it will ask for my phone number.  Upon entering the verification code the following message popped up "We are unable to process your request at this time.  Please contact customer support 1-888-764-3771".  The same mssage popped up when I try to set up on LG G4 and LG G5.  I checked with fido services and wifi calling were enabled on both my lines.

Please note both phones have the most updated phone software.

Does anyone encountered this issue and found a solution?

Thanks in advance.
