def stream(self, limit=None, page_size=None):

Streams PhoneNumberInstance records from the API as a generator stream.
This operation lazily loads records as efficiently as possible until the limit
is reached.
The results are returned as a generator, so this operation is memory efficient.

:param int limit: Upper limit for the number of records to return. stream()
                  guarantees to never return more than limit.  Default is no limit
:param int page_size: Number of records to fetch per request, when not set will use
                      the default value of 50 records.  If no page_size is defined
                      but a limit is defined, stream() will attempt to read the
                      limit with the most efficient page size, i.e. min(limit, 1000)

:returns: Generator that will yield up to limit results
:rtype: list[twilio.rest.proxy.v1.service.phone_number.PhoneNumberInstance]
