Roster update empty

Hi community,

I'm having trouble with a simple scenario involving cloud communication. I'm using directly the GRAPH API, without SDK.

A PSTN caller calls a bot, that answers then escalates the call to a conference by inviting a user from its tenant.

Sometimes, not always, the roster update is empty, then only the bot appears to be involved in the conversation. The caller is missing from the roster. As soon as the user accepts the call, a roster update is received, containing the caller.

Why would I create a thread ? It's because if the caller drops the call before the user accepts the invitation, I'd like to revoke this invitation. And it is not possible when this behavior happens cause no roster update is received.

In the samples below, two invitations to two distinct users are made for the same call. All times are UTC.

Here is a sample where the roster received is OK
