As a continuation of my project, I am trying to set up Kamailio as a
Websocket bridge to Asterisk. The asterisk instance is running as
localhost,
with its own websocket support disabled, but otherwise has accounts with
all
of the avfp and dtls settings for websockets. Additionally, I have
removed
the bindaddr=127.0.0.1 from sip.conf and instead put a
deny=0.0.0.0/0.0.0.0
and permit=127.0.0.1/255.255.255.0 in order to restrict SIP signaling to
localhost. This allows asterisk to bypass rtpproxy when signaling through
a
websocket. I have already established calls originating from the browser.
However, I have an issue with the registration.
Just in passing, why did you remove bindaddr=127.0.0.1?
If I keep the bindaddr, then asterisk fails to send the DTLS-SRTP handshake
packets, resulting in no audio. Apparently rtpproxy does not route this.
FWIW: I added a new setting into chan_sip, rptbindaddr[1], which
allows you to no control the interface RTP binds too. Not sure if
that helps in your setup or not.
In my setup, Kamailio receives the REGISTER from whatever source, and
forwards this through UDP to Asterisk, after the multiple-domain
transformation. Therefore, Asterisk sees the following in its SIP port
(all
traffic through localhost):
REGISTER sip:pbx.villacis.com SIP/2.0

Asterisk answers this through UDP, and Kamailio forwards it through the
websocket:

After that, Asterisk wants to send an OPTIONS packet. From the point of
view
of Asterisk (sip set debug on), it is already sent, but never gets a
response. However, tcpdump shows that the packet is never sent through
the
localhost interface in the first place. It is also not sent through any
other interface. My guess is that since the REGISTER has a contact with
transport=ws , Asterisk wants to send this through a websocket (which is
disabled). So I could have to generate a contact without transport=ws .
I have worked around this by setting qualify=no in the account for the
websocket, but I would like a better solution, one that allows the
OPTIONS
packet to reach the browser, and to get the response. What is the proper
way
to deal with this?
What does the OPTIONS message in asterisk look like?

Ya, your via address is over the WS. What does your peer settings look
like for avillacisIM_pbx.villacis.com ?

I think the situation is because of the change of transport. How should this be
handled so that Asterisk stops trying to use websocket transport for the
signaling that came from the UDP port?
