Dear ALL
 
   I  have two SIP Proxy servers , One is SER, another one is CSPS (cisco)
 
When I call a phone number that is belong to the CSPS routing, using the SER subscriber, the packet form SER to CSPS will get a problem with "400 Bad request" .
(It's ok, If the UA in CSPS call to the UA in SER)
 
My architecture is :
    UA1----SER----B2BUA---RADIUS
                 |
                 |
           Internet
                |
                |
            CSPS--UA2
              
 Logs of B2BUA :
 20060412-144443.276 [57396144] WARN bcWorker: uaState/UaStateRinging.cxx:133 UaStateRinging::Received 400
20060412-144443.276 [57396144] INFO bcWorker: controlState/StateCallReady.hxx:98 StateCallReady::bye was called, incomplete transaction
 
Does anyone know how to solve it?
 
thanks
 
AR.
