T38G pickup handset doesn't answer the incoming call

[Yealink Support]

Hi Daniel Velasco，

Would you please help clear below items:
1. Do you mean this issue won't occur every time when operator anser the incoming call? What is scenario while this issue occurs?
2. Why do you need connect 3 EXP38 to the T28 phone? Could you please export the config.bin file of your phone and send it to me?
Access to web GUI->Settings->configuration tab, click the export button and save the config.bin file in you PC. Then you can past it in this tread.

thanks
