Hi, again
I call the Korea polycom vender and I was asked to upgrade the telephone.
I tried,, althought it was hard.
I finally ugrade to 4.0.10.
The problem has risen again.
When I connect phone to my server(Frsip), the phone downgraded again(to 4.0.5).
Does Polycom 550 has the function that blocks the downgrade?
Thank you,
I use FRSIP for the PBX.
Currently using 4.0.5.
Mac starts 0004F25
