Visual alert for BLF Pickup doesn't work properly

[Mr_Christian]

Hi,

we are trying to get the visual alert for BLF pickup working. Unfortunately the displayed alert does neither show the name of who is calling nor the name of who is called. Let me explain it using an example:

Alice wants to call Bob. Alice has the internal number 40, Bob has the internal number 11. When Alice calls Bob, this is what we see on the display:

Code:

11 <- 11

What we would expect to see is:

Code:

Bob <- Alice

Or at least:

Code:

11 <- 40

When the call has been picked up, the name is shown correctly (Alice).

We are using a Yealink T56A with the latest firmware (58.80.0.40).

Is this a configuration issue (what have we missed then?), a bug or an issue with the PBX (Asterisk-based)?

Thank you very much for your help in advance!

Best regards
Chris
