[sr-dev] [kamailio/kamailio] Problem Parsing Route Header (#2079)

[duarterocha91]

Greetings,



Sorry about the confusion, the Routing works perfectly with multiple
addresses in one header. I think i have a better scenario now.



So, i have this SBC with 2 IPs (212.13.40.205 and 212.13.40.209) where in
INVITES i use uac_replace_from() and uac_replace_to(). Kamailio UAC’s
module is set for “AUTO” restore.



In this scenario, the original call arrives at Kamailio like this
(Restore.pcap) :

                From: 351211450093

To : 351258064574





The call is routed to my client and the packet leaves Kamailio like this
(Restore.pcap) :

                From: +351211450093

To : +351258064574





The info is stored in the “vst” and “vsf” parameters in Record-Route header
 ( Note :  Kamailio has 2 IPs) (Restore.pcap):







Later, i receive a BYE request from the client with To and From like this
(Restore.pcap) :



The To Header has “I2116446I_500” as user part which i think it’s still RFC
compliant. Regarding this i couldn’t find anything proving that wrong.



Here is where the problem  starts. If the auto restore is activated, the To
header end result is malformed  (Restore.pcap) :



If i deactivate the restore and a similar test, the headers are unchanged
 (NotRestore.pcap):







I have a couple questions about this :

                Are the vsf and vst alone enough to do a proper restore ?
If not, what inputs does it take ?

                Does the “AUTO” restore works if the client sends me a
different user than i sent him ?



Please find the captures mentioned in annex.



Thanks a lot for your help.



Best Regards,
