caller ID source --> display permanently

[wouternotebaert]

Hello,

we configured the caller ID source on our cloud pbx to show on the yealink device when we have an incoming call. the original call has "text @ display": "belfor"

however the caller id source is only shown for 1 second and then it disappears and shows only the number of the caller.

we have multiple tel numbers routed to 1 phone. we would like to see the original caller id permanently, so people know what phone number was used. as it is now, it is shown in a blink of an eye, so not usefull.

is there a way this can be shown in a better way on the device?

as shown in pictures the "Belfor" is shown only for 1 second and then dissappears completely.
"RBZ Wouter Notebaert" is the callers phone number wich is permanently shown.

kind regards.
