[OpenSIPS-Users] Forwarding ACK to 200 OK to itself.

[David Villasmil]

Hello folks,

I'm facing this issue on this scenario:

[ 1] USER---INVITE--->OPENSIPS
[ 2]                  OPENSIPS---INVITE-->STIR/SHAKEN (OPENSIPS)
[ 3]                  OPENSIPS<--- 302 ---STIR/SHAKEN
[ 4]                  OPENSIPS<--- ACK ---STIR/SHAKEN
[ 5]                  OPENSIPS-----------INVITE--------->TERMINATION
[ 6]                  OPENSIPS<----------  180 ----------TERMINATION
[ 7]                  OPENSIPS<----------  183 ----------TERMINATION
[ 8]                  OPENSIPS<----------  200 ----------TERMINATION
[ 9] USER<-- 200 -----OPENSIPS
[10] USER--- ACK ---->OPENSIPS
[11]                  OPENSIPS--- ACK
[12]                  OPENSIPS<-- ACK
[13]                  OPENSIPS<----------  200 ----------TERMINATION
[14] USER<-- 200 -----OPENSIPS
[15] USER--- ACK ---->OPENSIPS
[16]                  OPENSIPS--- ACK
[17]                  OPENSIPS<-- ACK


This only happens when I enable that STIR/SHAKEN functionality and use the
302, when OpenSIPS sends out the INVITE [

The 200 OK has this as a record route:
Record-Route:<sip:10.241.40.144;lr=on;did=277.5664>,<sip:OPENSIPS_PRIVATE_IP:4060;r2=on;lr;ftag=gK0467de76>,<sip:OPENSIPS_PUBLIC_IP:6070;r2=on;lr;ftag=gK0467de76>,<sip:OPENSIPS_PRIVATE_IP:4060;r2=on;lr;ftag=gK0467de76>,<sip:OPENSIPS_PUBLIC_IP:6070;r2=on;lr;ftag=gK0467de76>

what do i need to do to remove those duplicated record-routes after
receiving the 302?

Thanks alot for your help!
