A blank is heard during the playback of an audio message when escalating a call to a conference

Nivedipa-MSFT- I just used my cellular phone. I'm located in France.

All timestamps are UTC. I've hidden my company name, my company tenant id, and my personal phone number (XXX, YYY and ZZZ)

<<<<<<<<<< is a HTTP communication from microsoft cloud to my web site.

>>>>>> is a HTTP communication from my web site to microsoft cloud.

<<<<<< is a HTTP response from microsoft cloud
