CustomerEndpoint Address telephone number not consistent

When I call from my number +91 74XXXXXXXX ,for few times I see Customer endpoint adress is different telephone number like +161568623XX.

Out of 5 calls it is showing exactly my number 1 or 2 times only. Few months back when I used connect , it used to show exact number I'm calling from.

The start of your phone number, +91 is the country code for India. +1 is the country code for US and surrounding territories.

CustomerEndpoint will be a value of the number we receive from our telecom partners. A couple questions and areas to explore:

1. Are you forwarding calls in from another provider to Connect? This could influence the number shown to our system.
2. Are you sure you have correlated the correct call? You may be receiving actual calls from a US number.
3. Your telecom carrier for your +91 number could forwarding your call to a US based number before creating an outbound leg to the Connect service. Connect would not have visibility into that leg.

Out of above areas ,I belive it could be reason (point 3) with telecom carrier making that outbound leg to connect +1 troll free number.
