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@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@192.168.5.120>;tag=as246d1f36.
To: <sip:1920@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@192.168.5.120>;tag=as246d1f36.
To: <sip:1920@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 !

Thank you for your answer. I am a bit confused as when I tested with
other sip phones (sipura or some common soft phones), the reply come
right back to the server:

My openser have a private IP (192.168.5.119) statically natted to xx.xx.33.119;
so the first via contains the private IP. Is it up to the client to figure out
how to manage this or is there a way to handle this in openser ?
Thanks,

Look at the "Via" headres in both cases, they are the same.
You have an issue because NAT. The Thomson INVITE leaves OpenSer natted but
the Via header added by OpenSer says "192.168.5.119". You should fix the Via
header for messages that will be natted, but sincerely I don't know how.
AFAIK if not a very good idea (very complex) having OpenSer in a server doing
NAT.
