The number is correct. Once you are being transferred to CIC don't hang up after you hear "we are currently experiencing a high volume of calls" remain on the line and some instructions will follow. After you hear them you gotta end up with the sequence of these numbers "1111131" and at the end you will be given the approximate estimate of waiting time (mine was 18 minutes). If I am not mistaken, nothing is charged for the waiting so you should be OK. I was told that currently my background, in particular the clearance, is being checked and that my file is not transferred to the local visa office. As I have heard that the background check processing times are not under the control of CIC I did not ask how much longer it would take. Although, you can ask when to expect some news or whether everything is OK with your application but I personally believe that cases with issues are highly unlikely to reach the background check stage if the problem itself is not in the background ;D.
