My Polycom SoundPoint IP 320 shows the Caller-ID name while the phone is ringing, but as soon as I pick it up, the name is changing to the number. E.g. while ringing it says:

Call from: ACME WIDGETS(+14085551212)

but when I pick up the phone it says:

From:+4085551212(+14085551212)

I know I messed something up, but I don't know what. Any ideas?
