**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.

Hi @emason1  
Thanks for reaching out to us.  
Could you please share the tracking ID of the request you are sending and also can you try expanding the from and to dates to make sure all SMSs are included in your request.

When sharing the tracking ID of the request (found in the response headers) can you please expand on what messages you are missing,
