Hi,All
       When i am doing some interop betweem RGW and  third party Softswitch product,I found that the callee in  RGW side doesn't stop ringing   when Softswitch send Subtract + Modify to it. I know the callee will work well if Softswitch send command with Signal Descriptor SG{}.But currently,the Softswitch only  send  Subtract + Modify  commands  with embedded new signal descriptor to  RGW (see belowing message trace) Should  RGW  stop the current ringing  signal on  the  termination  according to protocol?   
Pls clear my mind on this topic.
