If you could provide some pointers on this that would be great.
I'm guessing the t_on_reply ("handle_nat") stays as is
While the branch_route[handle_nat] logic needs
Yeah, sorry, missed that one .
Well, it seems that OmniPCX is doing late SDP negotiation (via 200OK +
ACK, instead of INVITE+200OK) and the tutorial script does not handle
this case (for simplicity and clarity reasons).
So, right now the RTPengine interaction (the offer and answer) are done
As you may have noticed in my last reply, I reached that far as well but
got stuck later on on what appears to be the rtp engine configuration.
Not strictly an Opensips issue but you might be able to help me.

Hi Alex,
Thank you for the offlist provided data. Shortly, the ACK received by
OpenSIPS from OmniPCX is broken as it is missing all the Route headers.
According to the pcap, it looks like:
ACK sip:udoioiia@10.0.1.106:49246;transport=ws SIP/2.0
Record-Route:
Hi Alex,
As suspected, the ACK is not properly routed - see the retransmissions
of the 200OK + ACK. SImply based on the logs I cannot see what the
problem is - probably some missing fix_nated_contact() for the replies
coming from the WS party.
Please make a pcap capture + opensips log
Good, there is some progress :).
On the incoming calls, if the WS get's the call, we can park the part
with the auth (it seems your opensips script is accepting calls from
unknown sources...we can address this security hole later.
So, if a call drop after 30 secs it usually means there is no
I think I set up uac_registrant correctly.
I can dial out from a ws client and the ws extension rings from outside
calls.
However:
a) on incoming calls, when ws client accepts, there is no sound and the
line is dropped after 30 secs or so
b) on outgoing calls, when the called extension accepts
I checked the script you mentioned and it does not help you - it has
only UDP (no WS), it is really basic and it does not handle any REGISTER
stuff, which is the trickiest - see

Hello Bogdan,
First of all, thanks for your time.
Unfortunately my SIP/OpensSIPS skills are what I've managed to learn in the
last couple of days. I am a programmer but I've never had to work on SIP
stuff before.
Frankly to me, both solutions sound equally difficult since I have no idea
where
Hi Alex,
To make a kind of WS<>UDP gateway you need a complete rework of the
script presented in the tutorial, as it is a completely different SIP
scenario. Not sure what are your SIP/OpenSIPS skills.
But, there is a simpler alternative . Instead of a GW, you can make
OpenSIPS as a
Hello Bogdan,
Yes, a gateway from WS to UDP (as well as DTLS-SRTP to RTP in order for it
to work) is exactly what we're looking for.
Unfortunately our Alcatel OmniPCX call center is a proprietary system that
only allows for a limited number of SIP extensions (served from what
appears to be an
Hi Alex,
First, some questions regarding the desired topology:
1) the WS end-points should register in OpenSIPS or all the way
into Kamailio ?
2) also, the calls from the WS end-points should be all the time
sent to Kamailio ?
More or less, what I'm asking is : is OpenSIPS suppose to
Curious, why would you want to use OpenSIPS and Kamailio?
There both SIP proxies.

Hello,
We have the following scenario: our office call center is an Alcatel
OmniPCX Office setup.
This handles most of our needs and also provides 4 SIP extensions.
These are provided by what appears to be a Kamailio SIP server v 3.2.2 (no
webrtc or websockets support)
What we would like to do
