Try calling 155223.
Or message 'STOP' or 'HELP' to the same (155223) to get a grip on active VAS services.

Actually the BSNL specific IVR number or short code messaging number is different.
But I used NT (name tunes) many years back and now those numbers for activating, deactivating have changed I think.
Theoratically, it can also be set or stopped from the http://bsnltunes.co.in BSNL tunes website.
But then, even its promoters want to kill MTNL, BSNL
hence http://bsnltunes.co.in site process may not always be smooth.
