[OpenSER-Users] question regarding record-route and via

[vallimamod abdullah]

Hello list,

I am trying to understand why the thomson ST2030 hard phone does not work with
my openser.  I have noticed while ngreping that it seems to not respect the
record-route header.

I have the following incoming invite:

    U 2007/10/18 19:31:54.067545 xx.xx.33.119:5060 -> 10.0.0.136:15060
    INVITE sip:1920 at 10.0.0.136:15060;user=phone SIP/2.0.
    Record-Route: <sip:xx.xx.33.119:5060;nat=yes;lr=on>.
    Via: SIP/2.0/UDP 192.168.5.119;branch=z9hG4bKae88.af6caa.0.
    Via: SIP/2.0/UDP 192.168.5.120:5060;branch=z9hG4bK58e93388;rport=5060.
    From: <sip:6897 at 192.168.5.120>;tag=as246d1f36.
    To: <sip:1920 at 192.168.5.119>.


And the phone answers to the IP of the first via instead of the one in
record-route:

    U 2007/10/18 19:31:54.083370 10.0.0.136:15060 -> 192.168.5.119:5060
    SIP/2.0 100 Trying.
    Via: SIP/2.0/UDP 192.168.5.119;branch=z9hG4bKae88.af6caa.0.
    Via: SIP/2.0/UDP 192.168.5.120:5060;branch=z9hG4bK58e93388;rport=5060.
    From: <sip:6897 at 192.168.5.120>;tag=as246d1f36.
    To: <sip:1920 at 192.168.5.119>.


I would like to know the opinion of SIP gourous out there: is this
rfc-compliant ? I don't have this issue with other phones so I am wondering if
I should ask for a refund...

Thank you !
