custom.handset.auto_answer.enable not working

[Yealink_Michael]

hi samuel

thanks for your information

for this parameter , i have test in my side with the same firmware as your side, and it works just fine,

so please do the steps below :

1. reset phone and handset to factory
2. test using the auto provision file i attached

if all the above solution can't solve your issue, please provide us the trace file for future analysis,trace file including pcap file, config bin and syslog file , and we need three of them provide at one time.

for how to get them , please refer to the FAQ below:
