Caller id presentation info on BLF visual display
This topic was raised 12 months ago as part of thread:


It's important for call pickup and BLF effectiveness. It relates to the calling party information displayed on extensions in a BLF group for an external inbound call.

It works on a T46 but not on a T41.
It works on both T46 and T41 if the call is internal, therefore the basic capability is there but there's a bug in the T41.

If I create a BLF group with audio and visual enabled on:

1 x t46
3 x t41.

If I dial the external DDI of the T46 the BLF display on the T41s shows the the calling party and the target (t46) extension.

If I dial the external DDIs for any of the T41s the BLF display on all phones only shows: 838>838 which is the extension number of the T41 receiving the call.

it would seem that the T46 is able to feed the BLF payload with the calling party but the T41 is not.

I appreciate that Yealink marketing might consider this to be a way of luring customers to adopt T46s but this is not a good strategy as it undermines not enhances the t46.

We've tried the scenario on the current and previous firmware - The T46 is

I have the Pcap traces from the phones for the test calls and am analysing them.
