[Partysip-dev] Duplicate INVITE and BYE

[Pang, Thomas]

Hi all,

I am using partysip-0.5.0 with linphone-0.9.1.  Monitoring SIP messages
using Ethereal,
I realize that partysip folks INVITE and BYE twice.  Please see the
following traffic trace:

UA 1          Proxy           UA 2

INVITE ----->
       <----- Trying
              Invite  ------>
              Invite  ------>
                      <------ Trying
                      <------ Ringing
       <----- Ringing
                      <------ OK
       <----- OK
ACK    ------>

       <----- RTP ------>

BYE    -----> 
              BYE     ------>
              BYE     ------>
                      <------ OK
       <----- OK

                
Is it a bug or is there a reason of duplicating INVITE and BYE messages?
Thanks.
