Calling number presentation on unanswered and received calls issue


we are observing a very strange behaviour on multiple phones for  unanswered call coming from PSTN (same problem observed for a call  coming from a MGCP gaeway or a SIP trunk)

- we have 3 phone models : 9941, 7965 and 6941

- the calling number is transformed by adding a zero  (i.e. 070123456 is presented as 0070123456)

- the calling number is presented correctly in all the phones

- all the phones "see" the corrected calling number with the leading zero on prefix

- on 6941: there is no problem, on both received call history and unanswered calls one sees the calling number as "0070123456"

- on 9941: in the received call history the calling number is  0070123456, in unanswered calls it is stored as "070123456" (without the  leading zero)

- on 7965: in both received call history and unanswered calls the number is stored as "070123456" (without the leading zero)

I remark that the calling number that one sees on the three phone models has the leading zero...

Any help will be greatly appreciated
