Hey Klaus,

first, some answers :

-> when a thomson is the callee, there's no ringing even if indicated into the SIP message.
-> when a thomson is the caller, no problem, there's a ring, and the call is ok with audio.

Please be a bit more specific: What does "no ring" mean?
No "180 ringing" response from callee to caller?
"180 ringing" response but no "ring-back" at the caller's client?

oups, sorry, I mean : SIP messages are ok, there is all the sig process.

the architecture is :
linksys + thomson -> cisco 827 -> SDSL -> our backbone which have a firewall for VPN (so NAT and NAPT are applied here), then the kamailio with a public ip.

you have the 100 trying, 180 ringing in the SIP message, but there's no ring-back tone for the callee.

in the attached file :
linksys to linksys, where all the call process is ok (sip + rtp)
thomson to linksys, idem
linksys to thomson, sip ok but rtp apparently not.

I forgot the firewall for the vpn, rtp proxying is required, sorry - so yes rtp proxy must be used.

regards,

.Sam.

-> the SIP mesages are the same in the 2 cases.

incoming invite are exactly the same (but the source IP, and the "user=phone" parameter, for sure).
outgoing invite, in the 2 cases, replaces the source IP on the "c" line into the SDP by the RTP proxy IP (but at the end, it indicates a=nortpproxy:yes

a=nortpproxy:yes is fine. This line will signal to upstream proxies that an RTP proxy was already activated and there is no need to activate further RTP proxies.

Please post a complete ngrep trace (INVITE.....BYE) for the sucessfull and for the unsuccessful call.

Did I force 2 times the RTP proxy, or is there a

no

fix_nated_contact/fix_nated_register pbm ?

For REGISTER handling you use fix_nated_register. For all other cases you use fix_nated_contact.

BTW: What do you mean by "there's no RTP proxying" in the "not ok" case?

regards
klaus

really strange, I can send to you the kamailio debugs if you need it

in advance many thanks,

.Sam.

Hi Samuel!

What exactly is the problem when "not ok".
is signaling fine?
what is the audio problem (one way audio? no audio at all?)

compare the SDP of the incoming INVITE with the outgoing INVITE. If
you use rtpproxy, the IP address in the c line should be changed.

Hello,

ok, I tested this in the same LAN :

Thomson st2030 -> Linksys spa941 : ok
Linksys -> Thomson : not ok
Linksys -> another working Linksys : ok
Thomson -> another Thomson : not ok

Indeed there's no RTP proxying.
I check all the SIP messages below, the only differences I saw
are : "user=phone" and the rtpmap.
concerning NAT there are behind the same router, the location
saved is fine ?

in the kamailio log, the routing logic is the same.
registration of all sip phones are ok, proxy auth too.
the Thomsons can't find any other sip phones ...

here are all the invites (got with ngrep) :

Hello all,

I've a little problem with the SIP phone Thomson ST2030.
When it registers, it auto-adds ";user=phone" in all the

it can be.
The problem is that it can't be called due to the contact
header, kamailio can't found the phone.

I tried to delete the filed during the REGISTER and the PROXY
AUTH processes, with no success ...

If someone has a solution, many thanks !
