Attached to Project - sip-router
Summary - Added Record Route Header incorrect when Request-URI contains a SIPS URI
Task Type - Bug Report
Category - Module
Status - Unconfirmed
Assigned To - 
Operating System - Linux
Severity - High
Priority - Normal
Reported Version - 3.1

Due Date - Undecided
Details - The record-route header added by Kamailio to a SIPS (TLS) call using the record_route(); operation is incorrectly generated by Kamailio.
Page 101 (second sentence) of RFC3261 states
"If the Request-URI contains a SIPS URI [...] the URI placed into the Record-Route header field MUST be a SIPS URI."
Kamailio incorrectly generates record-route headers with the sip: URI scheme.
All other fields are correctly generated with the sips: URI scheme.

In response to this deviation from RFC3261, a Cisco ISR rejects the call with code 403.

Module rr source code in release 3.3.3 checked and problem is caused by  #define RR_PREFIX "Record-Route: <sip:"  in record.c

possible solution is check the Request URI for SIPS URI , and use #define RR_PREFIX_SIPS "Record-Route: <sips:"  instead.
