I see following sequence:
The message is sent:

There is no response for specified amount of time and we timeout:

As Yaniv pointed here is why we never get the response:

When we see timeout on a call our default behavior is to reconnect
when we clean pending messages.
As a result when we reconnect and receive a response from the message
sent before disconnect
we say it is unknown to us.
