T28P 2.72.0.30: Display shows wrong name/number in call history

[Benoiti]

Firmware: 2.72.0.30

The problem shows as follows:

1. 111 calls 102
2. The call times out (unanswered) and goes to voicemail
3. 102 checks voicemail (5102)
4. 102 checks call history, incorrectly shows "Spare Phone 111" as last call, but when pressing 'OK' to view details, the hotline number is voicemail (5102)
5. When checking the missed call underneath, "Spare Phone 111" shows the correct hotline number (111)

This is very confusing to the user, who tries to dial 111 through the call history, but ends up calling voicemail (5102) instead. See attached photos.
