I sit around and call one of Megaera's sisters (9)

I believe the answer is:

tisiphone

I'm a little stuck... Click here to teach me more about this clue!

'one of megaera's sisters' is the definition.
I can't judge whether this definition defines the answer.

'i sit around and call' is the wordplay.
'around' is a reversal indicator.
'and' means one lot of letters go next to another.
'call' becomes 'phone' ('phone call' can be a synonym of 'call'**).
'i'+'sit'='isit'
'isit' in reverse letter order is 'tisi'.
'tisi'+'phone'='TISIPHONE'

Can you help me to learn more?
