The fate of BlackBerry's encrypted email and messaging services in India will be decided in talks ahead of a 31 August deadline.
BlackBerry's troubles in India stem from government claims that its encrypted services could be used for activities from terrorism to peddling pornography.
BlackBerry's maker, Research in Motion, is being requested to give the Indian government the means to track and read its secure email and instant messaging services.
A ministry official said that deliberations will go on for the next two days and a final decision will be taken on Monday.
Last week, India said it will allow BlackBerry's messenger service to continue beyond the 31 August deadline after Research In Motion assured India of manual access to instant messages by 1 September and automated access by November.
But the interior ministry said it will shut down Research In Motion's secure email service if access is not given to its encrypted email data.
A shutdown would affect about 1m users in India out of a total 41m BlackBerry users worldwide, allowing them to use the devices only for calls and internet browsing.
RIM uses powerful codes to scramble, or encrypt, email messages as they travel between a BlackBerry device and a computer known as a BlackBerry Enterprise Server (BES) that is designed to secure those emails.
