[reSIProcate] webrtc/websocket branch test results



I've now had a chance to run some tests using sipml5, a webrtc
Javascript client running in a Chrome browser, against the b-webrtc
branch (r9980)

a) repro appears to struggle with the unusual domain in the Via header.
 The sipml5 client inserts the hostname df7jal23ls0d.invalid in the Via
header.  Hacking Tuple.cxx a little bit (see patch at bottom) got me
past this


INVITE sip:1004@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx SIP/2.0
Via: SIP/2.0/WS
df7jal23ls0d.invalid;branch=z9hG4bKHX0A65ARCtLsQ1XQKAzAU7IvRuydwnTV;rport=51523;received=192.168.1.114
Max-Forwards: 70
Route:
<sip:srv1.office.readytechnology.co.uk:5060;lr;sipml5-outbound;transport=tcp>
Contact:
<sip:1005@df7jal23ls0d.invalid;rtcweb-breaker=no;transport=ws>;+g.oma.sip-im;+sip.ice;language="en,fr"




b) sipml5 can register successfully using WS (WSS is not fully
implemented yet) and I see the user in the web UI


c) calling from a regular client (e.g. on TCP) back to the sipml5
client: repro tries to do DNS lookups on df7jal23ls0d.invalid, this
fails, it rejects the call.  It needs to behave as if using Outbound,
and send the INVITE to the client using the existing WS connection.


d) calling from the sipml5 client to 4 other SIP clients was
unsuccessful, but repro was not at fault.  repro correctly passes the
INVITE to the destination.  However, I observed the following:

- the Polycom IP321 reboots itself when it sees the INVITE from sipml5
(a useful party trick for SIPit next week?)

- Jitsi rings, but when I answer, it complains politely about no valid media

- Lumicall has an exception in Codecs.java

- Empathy rejects the INVITE

To summarise, I think there is more work to be done in reSIProcate to
integrate this feature, but there is also work to be done to find a
suitable peer that can accept calls from the WebRTC user.

Here is a sample INVITE from sipml5 proxied by repro:
