Websockets on Asterisk 11 and SipML5

[James Mortensen <james.mortensen@xxxxxxxxx>]

Hello,

I'm trying to register a user using sipml5 on Asterisk 11. I followed the instructions here:

http://thr3ads.net/asterisk-users/2012/08/1972342-Asterisk-Websockets 

I added transport=ws to my sip.conf file:

[3002]

username=3002

secret=XXXXXXXXX

host=dynamic

type=friend

context=test

disallow=all

allow=g729

;allow=all                     ; Allow codecs in order of preference

allow=ilbc

allow=silk8

allow=gsm

transport=ws

I also modified the sipml5 library so that the URL looks like this:  ws://example.org:8088/ws with the /ws at the end, as instructed.

Now, where I get confused is here:

"You will need to change sipml5 to use http://<hostname or IP address of 

Asterisk>:8088/ws as the URL. WebSocket is only available on the /ws path."

Did Joshua mean to say ws:// instead of http://?  Because I'm not aware of WebSockets working with http protocols, only ws protocols. Is there something I'm missing here?

The error that I'm getting in the sipml5 client is:  "Disconnected: Failed to connet to the server"  And that typo is not mine.

On the server, here is what I see from a tcpdump. The port appears to be open, but I'm not convinced that Asterisk is actually listening for WebSocket traffic:

tcpdump -v port 8088

18:57:03.051712 IP (tos 0x0, ttl 243, id 21320, offset 0, flags [DF], proto TCP (6), length 60)
    static-50-43-101-83.bvtn.or.frontiernet.net.63036 > ip-10-168-151-65.us-west-1.compute.internal.omniorb: Flags [S], cksum 0x4f7a (correct), seq 4055598050, win 14600, options [mss 1380,sackOK,nop,nop,nop,nop,nop,nop,nop,nop,nop,nop,nop,nop,nop,nop], length 0
18:57:03.051758 IP (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto TCP (6), length 40)
    ip-10-168-151-65.us-west-1.compute.internal.omniorb > static-50-43-101-83.bvtn.or.frontiernet.net.63036: Flags [R.], cksum 0xeaf4 (correct), seq 0, ack 4055598051, win 0, length 0

Is there something else I'm missing?  Please let me know what additional information you need from me.

Thank you!
