Does PJSIP mute early dialog when the UAC receive several SIP 183 for early media?

[Rodrigo Pimenta Carvalho <pimenta@xxxxxxxxx>]

Hi,

according to RFC 3960,

"

   If the UAC receives early media from different UASs, it needs to
   present it to the user.  If the early media consists of audio,
   playing several audio streams to the user at the same time may be
   confusing.  On the other hand, other media types (e.g., video) can be
   presented to the user at the same time.  For example, the UAC can
   build a mosaic with the different inputs.

   However, even with media types that can be played at the same time to
   the user, if the UAC has limited bandwidth, it will not be able to
   receive early media from all the different UASs at the same time.
   Therefore, many times, the UAC needs to choose a single early media
   session and "mute" those sending UPDATE requests.

...   Therefore, UACs typically pick
      one early dialog randomly and mute the rest. 

"

So I ask:

Does PJSIP uses to mute some early dialog if the UAC receives multiple SIP 183 for early medias, in case of a forked call?

If yes, is there a way to turn off such behavior of the UAC?
