When placing two calls into an Aastra handset (tested with 6755 and 6757), whilst call waiting is active, the second call is presented first on screen, despite this not being the first call into the handset.
Fault can be replicated by having a single handset, placing 2 off-net calls in one-by-one and you will see that L2 becomes the dominant call on screen. Ideally, L1 should show. it can only be switched back and forth by using the left and right keys on the handset, or pressing the L1/L2 button on the handset.
Is it the defined functionality or can we change this?
