A solution to security concerns on BlackBerry has to come from Research in Motion, a top Bharti Airtel executive said on Friday, adding that operators like itself can only co-ordinate efforts.

Sanjay Kapoor, the mobile operator`s chief executive for India and South Asia, also said he expects a reasonable solution to the standoff between India and the BlackBerry maker.

Research in Motion faces an Aug 31 deadline to give Indian authorities the means to track and read BlackBerry Enterprise.
