Help Lollipop call thingy

[funkylogik]

Ok this is 1st time I've experienced this and I don't know if it was via Facebook or a normal call but while it was dialing it gave me the option of like "half an hour, an hour, an hour and a half" can't exactly remember but I hit 'half an hour " because I CBA talking.
Anyone any idea what it was?
Cheers
PS it doesn't show in my call list
