Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble.
If you start a call on speaker, then switch to the handset, can the other caller still hear you, even if you can't hear them?
You should be able to toggle back and forth by using the SP button, are you saying that won't work either (understanding that you likely won't hear them, I just want you to test to see if they could still hear you or not)
Do you need more help with this?
