[Serusers] faster SER

[Daniel-Constantin Mierla]

There is nothing to improve in SER as long the communication was 
established. In the case a NAT would be involved you would need either a 
RTP relay (rtpproxy, media proxy) or in some cases just a STUN server 
(depending on SIP clients and NAT type).

Try to force the SIP clients to use some other audio codec (if they 
support more than one) -- maybe one has a broken implementation of the 
codec chosen for communication.

I do not know much about asterisk, it may do some media correction or 
codecs translation.
