[Serusers] new MediaProxy release 1.4.2

[Adrian Georgescu]

Hello,

There is a new MediaProxy release available. Beside bug fixes the  
most noticeable improvement is the possibility to change the source  
of the party who signs in after an initial 183.

Changes from version 1.3.1 to 1.4.2
-----------------------------------

- Accept the called party to change the media streams sign-in address.
   This is useful for example if the "200 OK" comes from a different  
device
   that the "183 Session in progress" (for example if a call to PSTN  
that
   is not answered is then diverted to an announcement on a media  
server).
- Do not allow the control stream traffic to reset the idle timeout  
counter.
- Handle the situation where mediaproxy sometimes died with an  
OverflowError.
   This happened very rarely and the error backtrace doesn't make  
much sense.
   it seems like an obscure error in the underlying C select module  
and the
   OverflowError exception only seems to hide the real issue).
- The proxy dispatcher will test that a mediaproxy is actually  
responding
   to commands, not only that the mediaproxy TCP port is open, before  
choosing
   a mediaproxy to use. This solves issues with systems that die and  
stop
   responding, while the TCP port is still kept open by the operating  
system.
- Improved and optimized the mediaproxy server lookup procedure.
- Fixed bug with proxy dispatcher never actually running the timer that
   expired stale sessions.
- Rewrote the session expiration timer to run in a different thread  
at an
   interval that can be specified in the configuration. This will  
improve
   accuracy it as it no longer depends on receiving commands from SER  
to run.
- Also report proxy version with the status command to avoid the need  
to run
   the version command as well when requesting status (if version is  
needed).

There is no change required for the SER module or ser.cfg configuration.
