Intermittent handset pickup triggers speaker

[Kevin_Yealink]

Dear,

This is Kevin from Yealink support team, nice to know you.

For this issue, do you mean B transfer a call(with A) to C, C answer the call from B, but when C pick up the handset, the call is answered, but the sound will out from speaker not handset, so you should press speaker button again to change the mode to handset, so you can use the handset to talk with A, right? Let me know if any misunderstanding.

Also, can you tell me the firmware of C phone(T46,right?)? And can you upgrade it to the newest firmware, then reset the phone by long pressing OK button to test again.

if the issue still exist, please send pacp,syslog,config.bin files to me, then we do more troubleshooting. For how to get them. please refer to the FAQ:http://support.yealink.com/faq/faqInfo?id=311
NOTE:please reproduce the issue, so you can get useful information.

BTW：how many phones do you have? how many phoens have this issue?

BR
Kevin
