[Kamailio-Users] Announcement Server

[Bruno Rodrigues]

Hi All,
   First, sorry I have a bad english.
   Second, Anybody know if is possible redirect the call to one 
MediaServer when the destination answer the call?
   In the Media Server, the callee will hear  a announcement, and the 
destination will hear a another announcement. The announcement has the 
same duration.
   When the announcement finish, the RTP will be established between the 
UA1 and UA2
   The signaling I think will be this

UA1                 Kamailio               UA2             Media Server
Invite 
----------------->                                                                          
- Received a normal Invite
                               Invite---------------->                  
                          - Forward The Invite
                               
<------------------200                                              - 
Receive the 200 OK
<------------------200                                                   
                          - Forward the 200 OK
<-------------re-Invite re-Invite ------------>                        
                    - Kamailio will update the media part to the Media 
Server
                                                         <----RTP 
Announce 1----->        - RTP are established

<----------------------RTP Announce 2 
--------------------------------->       - RTP are established
<-------------re-Invite re-Invite ------------>                        
                   - Kamailio after the announcement are finished update 
the Media part to UA1 ip media and UA2 ip media
<-----------------RTP------------------------->                        
                    - RTP between UA1 and UA2

If have another way to do this, please let me know
Thank You in advanced
