Does anyone have tried these new grandstream BT models?
Don’t you have the same problem when you test a new one compared with an old one?
Please help me. I need to by more than 50 phones and the test phones that I bought are from the new model and they are not working well.
I’m using firmware 220.127.116.11 and I’m making tests whit old BT models and the new ones, with the same firmware and version 1.0.518 to.
My Client does not want to approve the solution with this problem on the new BT model.
I don’t have any problem with the old BT model on the same server, network, etc, etc…
BT sound quality has no “cuts” or noise. But the sound is much more “lower” and not clear and crystalline.
I’m using PCMA and I have tried several codecs.
If I only turn on the speakerphone the line sound on an “old” BT is much higher than on a new one…
