BAPI_USER_CREATE1 Mobile and telephone

Hi , There is a requirement to create users in SU01 by BAPI_USER_CREATE1. There we need to save the mobile and telephone number (without extension) of the user . The problem is when i give phone number in ADDRESS-TEl1_NUMBR(import param) , it is working fine.

But when i give the mobile phone number by filling ADDTEL-TELEPHONE,EXTENSION,TEL_NO(tried in multiple combinations) and set the R_3_USER to parammeters as 1,2,3 , i find it is making the problem in the ADDRESS-TEl1_NUMBR (ie the telephone number is not getting saved)

Help needed in saving both the mobile and telephone number of the user.
