Dear All,

I have the call 302 related call flow..

Source UA ----INVITE---> SBC -----------------------> Termination UA
UA <-----100 Trying           |
                                      | --------------INVITE--------->
                                      |  <---------- 100 Trying--------
                                      |
<---------302-------------------------
                                      |----------ACK-------------------->
 <----------302---------------     |
  ------------ACK---------->     |
                                     |
--------Re-invite------------>   |
<---------100 Trying---------  |
<------------404 Not Found |

Now the problem is that,,whenever my source UA sends the "re-invite" with
new "user" and the below REQUEST URI, then my SBC is sending 404 NOT found..

Request-Line: INVITE sip:2017%[email protected]:5060 SIP/2.0
To:<sip:2017%[email protected]:5060>
Contact:<sip:208.85.184.68:5060>

I checked the request URI and noticed that user part have the "%", on which
i have doubt. Could any one please suggest me what could be the wrong.

Here is the reason which i know.

1)  Either the user which is indicated by request uri are cannot be
located...
2) Or its signed off for time being.

Thanks,
Nitin Kapoor
