Description
We are using the Phone SMS Sessions API to capture all SMS sessions in our environment for archiving purposes. When we attempt to capture all sessions within a given timeframe, there are sessions that are missing from the API response.

Error?
No errors applicable.

How To Reproduce
Steps to reproduce the behavior:
1. Generate some SMS content with text, images, emojis, etc. This data should contain SMS with only one person & SMS with a group of people.

2. Call the phone/sms/sessions api with the designated timeframe of collection.

3. Notice that not all sessions are included in the API response.
