Dear all,
A customer of ours purchased some M30 cordless phones (sold and shipped by Amazon) after checking their compatibility with the M700 bases, which would require firmware version 530.10

The customer complains about poor audio quality, such as hearing his own voice when he speaks, with the M30 phone, and so I thought a firmware mismatch was the cause.

I updated as per the instructions, first the bases to 530.10, then the cordless phones, however the two M30 cordless phones in question have version 611.1 pre-installed and it seems that the downgrade to 530.10 is not possible. Under "FWU Progress" the message "Awaiting other FWU" appears

What could be the cause of the poor audio quality of the cordless phone?

I understand that in the 740 update release notes, which is incompatible with the M700 base, I read "small audio distortion improvement on snom M30"

How can I fix this?

Best regards
