Hello,

We need to review this in rr.

Meanwhile you can use s.substr transformation to get whats after sips and prefix it with sip in r-uri.

Cheers,

Found the problem, on the 200 OK, I have this record route list

Record-Route: <sips:<K2 IP>:6056;transport=tls;r2=on;lr;ftag=as620b910c;did=242.fd92;nat=yes>.

Record-Route: <sips:<K2 IP>:6055;r2=on;lr;ftag=as620b910c;did=242.fd92;nat=yes>.

Record-Route: <sip:<K1 IP>:5080;lr=on;did=242.968>

the second entry is wrong. it should be sip: and not sips:

how can we force this? protocol pv is read-only

Hello,

doesn't the ACK have a Route header for K1 and double Route headers for K2? K1 should use the first Route of K2 for routing, not the R-URI.

I have 2 kamailio servers and 1 asterisk server.

1. asterisk calls kamailio1

2. kamailio1 relays INVITE to kamailio2

3. kamailio2 relays INVITE to client registered using TLS

4. client answers with 200 OK, sends to kamailio2

5. kamailio2 relays 200 OK to kamailio1

6. kamailio1 relays 200 OK to asterisk

7. asterisk sends ACK to kamailio1

8. kamailio1 complains "forward_request(): forward_req: ERROR: cannot forward to af 2, proto 3 no corresponding listening socket" which is because 200 OK has a contact header with tls transport from client

9. call drops in 30 secs which is expected because client never received the ACK

any ideas on a fix or workaround?
