Cannot call into Teams meetings with conference phones

[rdavis61]

All of a sudden something in Teams changed and we can no longer call using the Teams conference number from our Cisco IP phones.  When we dial the number, we get a prompt to press 1 for English, press 2 for Spanish.  When we press the number on the keypad, Teams is not recognizing the tone.  This was working fine a couple days ago but all of a sudden we now get this prompt and can't join the conference.  Anyone had an idea how to fix this, or have you experienced this?

@rdavis61, I am not aware of a workaround you could use, but I was able to find the highest vote feature request representing your needs. Easy, streamlined, way to invite all of the team to a meeting – Microsoft Teams UserVoice Make sure to vote, I did so too! :)
