[SIPForum-discussion] second INVITE after 407 error

[FCG Xiao XiaoHong]

Hello, if UAC gets a 407 response, it means the proxy requires UAC to begin authorization procedures.

Hi Somesh,

 

Thanks for your quick response.

 

Not sure I understand. Are you saying it is valid for the UAC not to include SDP info in the retry INVITE after receiving a 407 response from the proxy? 

 

Thanks

Deepak

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.

Hi,

 

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
