PHLO: Inbound call failures — sub-account numbers on main account PHLO apps

Update timeline

   Dear Valued Customer, We observed some inbound calls to PHLO applications were not being processed successfully. This affected a specific configuration where a phone number rented to a sub-account was attached to a PHLO application owned by the parent account. A recent deployment introduced a change in the request authentication flow that did not account for this configuration. The issue has been identified and fixed. Customers using phone numbers and PHLOs directly under their main account were not impacted.
