With Julielai's definitions, I would conclude that...
'Voting' is to 'roll call' what 'termination' is to 'cloture'.
In this case, the reference is a 'roll-call vote'--a special form of voting where the name of each person in the voting pool is called out loud for a vocal response from that individual of 'aye' or 'nay'.
Thus, roll call is a special type of voting, and cloture is a special form of termination.
