[Sipp-users] loop control

[Peter H. <PH...@se...>]

Hi, Dear Expert,

 

Can anyone tell me how I can create the following scenario on the client
side?

      INVITE ---------->                                      

         100 <----------                  

         300 <----------                        

Duplicate INVITE ---------->                           

         300 <----------          

          ACK ---------->                                      

The problem is here:

I send out the duplicated invite once I received 300 from redirect server,
since I will receive 300 again, then the SIPP will go to loop and send the
invite again and again. I don't want to send the invite again and again and
go to loop; I want to send ACK instead after first retransmission of invite.
I use the start_rtd and rtd to define the timestamp, but I don't know how I
can control the loop. Thank you very much for your help.

Regards,

Peter Huang
