Specific filtering with Mysql

Question

Hello, my friends.

I have a mysql database,

and I’m making some appointments

I want to know how I can do a very specific filtering.

For example, I have a database:

+--------+------------+----------+-------------+
| callId | callDay    | callTime | disposition |
+--------+------------+----------+-------------+
|      7 | 2020-12-18 | 08:00:00 | ANSWERED    |
|      8 | 2020-12-18 | 08:00:00 | NO ANSWER   |
|      9 | 2020-12-18 | 08:00:00 | BUSY        |
|     10 | 2020-12-18 | 09:00:00 | ANSWERED    |
|     11 | 2020-12-18 | 09:00:00 | NO ANSWER   |
|     12 | 2020-12-18 | 09:00:00 | BUSY        |
|     13 | 2020-12-18 | 10:00:00 | ANSWERED    |
|     14 | 2020-12-18 | 10:00:00 | NO ANSWER   |
+--------+------------+----------+-------------+

In the case of this example database, I want to collect all records, but I want to omit the repeated values within the "callTime" column, or print only the "callTime" records in which there are more fields according to the "disposition" column, this is possible?

Gostaria que saída fosse mais ou menos assim:
+--------+------------+----------+-------------+
| callId | callDay    | callTime | disposition |
+--------+------------+----------+-------------+
