Hello,
I have a few questions about the websocket module which I have successfully installed but I wasn't able to make calls through it:
1. After setting up the proxy ip:port in the call.htm file (of sipml5) to
127.0.0.1:5060 the client started to work but kamailio script refused to establish my connection because the following condition was not satisfied:
if ($Rp != MY_WS_PORT && $Rp != MY_WSS_PORT) {
xlog("L_WARN", "HTTP request received on $Rp\n");
xhttp_reply("403", "Forbidden", "", "");
exit;
}
MY_WS_PORT and MY_WSS_PORT are set to 80 and 443 respectively, as the default config example of websocket module says so.
Then, I decided to change the ip:port to
127.0.0.1:80, always in the call.htm file and afterwards the condition was satisfied but sipml5 dies with
Unexpected response code: 200 :1
Failed to connet to the server
Finally, I ended up commenting the condition block and restored the original values of ip:port to
127.0.0.1:5060 .
Having done that, I tried again and another error was thrown but this time, in the next condition block: if ($hdr(Host) == $null || !is_myself($hdr(Host)))

I commented the block too and only then sipml5 was able to register itself.
What am I doing wrong here?
2. I registered a legacy softphone (twinkle) to attempt to initiate a call in both ways, but the was something wrong with the signaling, probably some frame decoding garbage in the buffer of the SIP message. Perhaps these bytes are part of the frame control header but since I haven't read the RFC (yet) I am mentioning it anyway.

3. Does Twinkle support the minimum media requirements for testing? If not, what (Linux) softphone is suitable for this purpose?
Thanks and sorry for the long email.
Carlos.
