n900 has trouble with the similar phone numbers like 10 years old mobile phones (and please don't say "it's not a phone!"). for example:

john doe 0552XXXXXXX
jane doe 0532XXXXXXX

everytime when jane calls it says john calling! i try to send an sms to john, typing the number manually, john gets it but my conversations screen says it's jane

thanks for further help and sorry for my bad english!

The numbers "0039340xxxx", "+39340xxxx" and "340xxxx" are the same number, but the first two have the national prefix in two different way. Therefore, the phone couldn't make an exact comparison of the phone, because if your phone book contact has the number "340xxxx", but when you receive a call/sms the operator send you the number "+39340xxxx" the phone doesn't recognize it, because "340xxxx" is different from "+39340xxxx".
The fastest solution (workaround) to fix this issue is to choose a number of digits big enough to recognize the number uniquely in the 99% of case as the probability that the same user has two almost equals number (different in the first few digits) is really really low.

Then, their solution is quite good, but not perfect and you are really unlucky to be in that 1% not covered by the workaround
