[SR-Users] Route Header - Comma separated issue

[Soltanici Ilie]

Hi all,

Why Kamailio are not removing full Route header in case if he is receiving comma separated Route?
For example: 
Receiving such Message:

SUBSCRIBE sip:101 at 192.168.1.1 SIP/2.0
Route: <sip:192.168.1.1;r2=on;lr=on;ftag=fb0076047b3da3e4;nat=yes>, <sip:172.16.30.10;sbc=topoh-NFlx.VXxPVXv8rfM83X1KnhF83LINVLO8VcJ6VL79zkEYH5U83hdKVhyKFi-5zX-5njs67kyYSllNx**>
Event: dialog
User-Agent: Cisco/SPA504G-7.6.2
Content-Length: 0 after applying loose_route function, kamailio is forwarding this message:

SUBSCRIBE sip:101 at 192.168.1.1 SIP/2.0
Route:
Event: dialog
User-Agent: Cisco/SPA504G-7.6.2
Content-Length: 0

Other devices are sending 2 Route Headers in separate rows - and everything is working properly.

Is this a bug or it should be like this per RFC?
Thank You.

using Kamailio 5.0.3.
