[SR-Users] Missing Route headers in locally generated BYE

[Carsten Bock]

Hi,

why should Kamailio add a route for himself to an outbound request?
172.30.105.18 is obviously the proxy itself; so adding the
Route-Header makes no sense.... (at least from a SIP-Perspective).

Record-Route: <sip:172.30.105.18;lr=on;ftag=ervXH3ycHcgpK;vsf=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA--;proxy_media=yes;dlgcor=fa8.9ea>

03:27:37.464071 IP 172.30.105.18.5060 > 172.30.105.20.5060: SIP, length: 367

Or am i missing something here?

Kind regards,
Carsten
