[SIPForum-discussion] second INVITE after 407 error

[Somesh S Shanbhag]

Hi Deepak,
  
  I think this is valid. The other side MUST include the SDP offer in  final successful response (preferably 200 OK) and UAC MUST include  answer in ACK which follows the response.

    Has anybody  experienced the following problem?
     
    My UA is sending  an INVITE to another UA with SDP info using the public proxy iptel.org.
     
    The first INVITE  gets a 407 error from the proxy .so my UA resends the INVITE but this time  without the SDP info. So the other side has no clue
    How to set up the  RTP media stream.
     
    My UA is using  Radvision stack .Has anybody seen this kind of a problem before.
     
    Thanks
          
    Deepak
