Apologies if I am repeating anyone but I have only just joined this list ......
We (Ubiquity) completed the Multi-Stage Proxy as P1 getting successful SIP
signalling to set up a call but I am not sure what happened at every point
downstream.
We also got successful multicast registers from HP Labs UA but there was nobody
else for them to the invite.
Finally we managed to setup the loop detection scenario with our proxy and
3Com's proxy. Both parties could play as P1 and P2 completing both the real
loop and 'spiral' case.
We also did request merging but using four instances of our own proxy so I am
not sure this counts under bakeoff rules.
As a general observation it seemed to me the bakeoff was more useful for
testing User Agents than Proxies. Probably because it is easier to test UAs
through basic call setup scenarios whilst testing a proxy generally requires
setting up >1 proxies plus many UAs. This was a shame because to debug the
protocol further I feel we really need to run scenarios involving networks of
SIP servers. Perhaps at the next bakeoff we can try and prearrange implementors
roles in scenarios so that people turn up better prepared to setup and go. It
might also help if we just ran one reliable UA in the proxy oriented tests.
In the meantime I am setting up our proxy server to be accessible over the
Internet. I know some other people have already done this and others are
planning to. Would anyone be interested in discussing building a network of
these public servers?
If anyone is really keen to test against us further I am happy to make our
Proxy accessible from a temporary location while I work at finding it a
permanent home. Particularly if you have a proxy and would like to try some of
the more adventurous scenarios mixing in Record-Route, Max-Forwards, Via hiding
etc
Cheers,
Neil
