128. I'm not sure whos teaching you about metadata, but you might want a refund...

This is exactly this type of information they are collecting... Note - it contains the phone numbers at both ends of the call.

https://en.wikipedia.org/wiki/Call_detail_record

A call detail record contains metadata – that is, data about data – containing data fields that describe a specific instance of a telecommunication transaction, but does not include the content of that transaction. By way of simplistic example, a call detail record describing a particular phone call might include the phone numbers of both the calling and receiving parties, the start time, and duration of that call. In actual modern practice, call detail records are much more detailed, and contain attributes such as:[2][3]

the phone number of the subscriber originating the call (calling party)
the phone number receiving the call (called party)
the starting time of the call (date and time)
the call duration
the billing phone number that is charged for the call
the identification of the telephone exchange or equipment writing the record
a unique sequence number identifying the record
additional digits on the called number used to route or charge the call
the disposition or the results of the call, indicating, for example, whether or not the call was connected
the route by which the call entered the exchange
the route by which the call left the exchange
call type (voice, SMS, etc.)
any fault condition encountered
