After some operations I have a series that i got after grouping by phone number and counting different calls. I need to count the phone numbers that have an equal number of calls. I mean, if there is 5 people who made 3 calls I need to get a series or a dataframe looking like:

num_calls 

3    5

1    100

...

My series now looks like

phone_num 

89248089190  5

48048102481  6 

12948148014  2

14091404108  5
