speaker on auto answer

[Lucia_Yealink]

Can you check for me what is the model and firmware version of the phone?
How many phones have the problem?

If the model is DECT(W52 or W56), then you can use the parameter via auto provision below to disabled the handset auto answer:
custom.handset.auto_answer.enable=0
If the phone model is not DECT, then please provide the level 6 syslog, config.bin and pace trace for me to double check, i wil use your configuration to do test in my local side.

Thank you.
