This is the number where sponsor is supposed to call from inside the Canada. They just ask you the basic info for the security purpose.
All one needs to give is client ID( if already have one), type of sponsorship, DOB, Country of Birth, Date application received, Principle applicant's name, type of application ( outland/inland), and spouse's country of living.
[ KUKU, Thanks for the info]
