Hi David,

IMHO, you do record_route() in request route (before sending to SS) and once again later, in failure route, after SS, before the Termination. Could you check this?

Normally doing it in request route is more then enough, covering the whole call processing; there is no need to do it per branch or so.

Hello folks,

I'm facing this issue on this scenario:

[ 1]USER---INVITE--->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!
