We have set up our second remote worker with a 5330 Phone connecting to a CP 5000. Setup seemed to go smoothly, but when she makes a call from the phone, she cannot hear the person she called through the handset. Everything works fine through the speaker on the phone. I have double-checked all the places that NAT is set up in the system, including the endpoint settings. Everything is as it should be, yet there is no two-way audio through that phone's handset. She can hear everything fine if it is on speakerphone.
We have another worker with the same setup, and her phone works perfectly, so I know our firewall settings are good.
I am mystified. Has anyone seen this or have a solution?
Thankyou.
