      Hi All,
   I have a small doubt regarding the SDP negotiation between a User Agent Client - UAC & User Agent Server - UAS. The below is the setup.
  UAC Configurations:  1st  priority     PCMA (A-law) 
                                  2nd priority     PCMU (U-Law) 
  UAS Configurations:    1st  priority     PCMU (U-Law)                                   2nd priority     PCMA (A-law) 

  If UAC sends INVITE with Codec supporting PCMA (A-law) and PCMU (U-Law) with PCMA has high priority as per the above configurations, how does the SERVER should respond? Does serevr should consider the priority of its own first or it should consider the priority of the client first .... Both server and client can support both U-law & A-law but only the priority changes..
