T22P disable call timer

[lexus45]

Hello. My first message here. I haven't started a new thread - advanced search helped me.

We bought 50 T21P phones. The situation is the same - when the conversation is active, the caller id number is not shown fully because of the big digits of call duration.

Our PBX is configured in such a way, that the caller id number is shown this way: Office-XXX <country_code city_code city_number> <caller's number>, e.g.:

Code:

Office-001 73522608294 7922573xxxx

And the last number - the caller's number - is displayed only before answering the call.

Is it possible to change the size of call duration digits?

Tried 34.72.14.3 and 34.72.14.5 firmware. I decided not to try firmware designed for T20 ot T22, I think it may be risky.

Thank you.
