[Serusers] Instant messages directly from sender to receiver

[Jffdsaklj dsjk]

Is it possible to configure SER in order to avoid that instant
messages go through SER, instead of directly to the receiver of the
message?.
After opening a session for instant messages, we have to send a lot of
instant messages. In order to improve the performance, it would be
recommendable that these instant messages don't go through SER proxy,
as the video/audio streaming does.
