[Users] ReInvite send twice

[Stefan Römer]

Hi !!!

I'm using OpenSER 1.0.1 and realized some strange behaviour
when SIP UA sends ReInvite Messages.

Initial INVITE shown below (this is OK)

UA A                    OpenSER                         UA B
_____________________________________________________________

--------INVITE------------> -----------INVITE------------>

<--------200 OK----------- <---------200 OK----------------

---------ACK-------------> -------------ACK--------------->




But when an UA sends a ReINVITE message I realized following behaviour.
This happens approximatly every 3rd or 4th ReInvite.

UA A                    OpenSER                         UA B
_____________________________________________________________
--------INVITE------------> 
                            -----------INVITE------------>
                            -----------INVITE------------>

<--------200 OK----------- <---------200 OK----------------
<--------200 OK----------- <---------200 OK----------------
     .
     .
     .
     .


Is there any reason for OpenSER sending ReINVTE twice?
Any chance to avoid this?


Sincerly

Stefan
