Try to join Google Meeting on home Obi 200 Google Voice # (corded and portable phones) and meeting portal doesn't recognize (hear) key press for PIN to join meeting. Keeps asking to enter PIN#.
Tried from a non-linked cell phone using a separate Google Voice number and works fine.
Tried again with Obi and same result, doesn't hear key press and can't join meeting.
Thoughts?
Under the ITSP Profile for the SP you are using there is the parameter DTMFMethod. There are 5 options. Try each of them.
