The option to Call...|Sneak Out appears between 10:00PM and 1:00AM. Pickup is at 1:00AM. There has to be an eligible sim to Sneak Out with in order for this option to appear and neither sim must currently be scheduled to sneak out with someone else.
The option to Crank Call appears during the same time frame, except your sim's niceness score must be 4 (out of 10) or less.
In the course of investigating this, I did uncover a bug in the InTeenimater that prevents pregnant teens from sneaking out. If your teen is pregnant, this could be the reason you don't see the option. I've posted a hotfix
here. Make sure you get the OFB-Seasons version (since your latest EP is Pets).
