RE: T28P incoming call bip when already on line
Hi julien,

Sorry for the late reply.
According to your description, may I have the following answers for further analysis?
1.What is the firmware version of issue T28? If it not the latest version,please upgrade it and test again. T28_firmware
2.How often does the issue happen, always?
3.How many T28 have the issue?
4.Have you ever tried to reset the phone to factory?
5.Does this issue happen no matter the other part is internal call or external call ?
Thx
