Hi Assistable fam - I have one of my first clients who's account has been on auto pilot for a year - working great - so entirely untouched for past 6 months. Found out they haven't been getting calls for the past several weeks - so I called the number and got a BUSY SIGNAL. Re-authenticated the OATH to all accounts...reconnected all accounts and still BUSY. When I purchase a new number to test - the new number works. QUESTION: did I miss the boat or memo that past numbers don't work anymore? Thanks for ANYONE with an answer - I appreciate it! @Hari Prathap Balamurugan @Jorden Williams
