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

[Alex Balashov]

I just tested this with dialog timeout and can confirm that there are no 
Route headers in the locally generated BYEs.

The Record-Route set for the dialog is:

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

The BYEs from Kamailio don't have a Route header at all.  Just these:

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

CSeq: 1 BYE
Call-ID: 34fdb244-dce1-1231-ee8e-00163e6490b7

Of course, that doesn't stop them from working.
