Bug Fixes
===========================================================
 . URI parameter in Authorization header may not matching request uri.

 . SPA ignores STUN responses if the message is larger than 64 bytes

 . OOB DTMF via SIP INFO still transmitted when call is on hold;
   result is that holding peer can hear DTMF as caller dialed 
   3rd party in a 3-way call.

 . SPA does not include all available codecs when transferred; it only includes a 
   trimmed down set as a result of the original call establishment. 

 . <Dial Plan 8> does not work for VOIP to PSTN calls

 . After entering invalid PSTN pin, next PSTN PIN tone does not time out
   until a new PIN digit is entered.

 . SPA does not support compact form SIP EVENT header 'o'. 

 . SPA does not support changes in SDP in successive SIP 183 responses.

 . Support <No UDP Checksum> (SIP) option for outbound RTP packets

   Refer Target respectively.

   to use the Refer Target's contact or it's public address
   in the Refer-To header of the REFER request when the SPA acts as the
   referor.
