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.
-> 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

what's wrong here ???

*** here is the incoming INVITE :

Did I force 2 times the RTP proxy, or is there a fix_nated_contact/fix_nated_register pbm ?

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 fields

       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

       If someone has a solution, many thanks !
