Many thanks for answering my question.

Can I ask a couple of questions about 'call in on' as I couldn't find it in dictionaries?
Does this idiomatic expression have any different meanings?
If so, in what context should I use it?

...Hope you don't mind me asking one more question...!
Is 'call in on' used as common as 'call on'?
Thanks for your help in advance.
