In version 4.0.1-015537, when I register from a remote NATed phone, I'm
seeing OPTIONS requests from sipXecs (I assume they are coming from
sipXproxy). I have a question and a comment about these:
* They set all four addresses (request URI, To, From, and Contact)
to 'sip:[email protected]' - why?
This isn't a valid address for my UA - since the proxy knows the
Contact I registered, wouldn't it be better to use that for the
request uri and To headers and put a fixed reserved address in
the From and Contact headers?
I know we don't care whether or not this request 'succeeds',
since the only point is really to elicit some response and the
404 my phone is sending is as good as any other for that, but it
seems it would be better not to have error responses in logs if
we can avoid them without too much work.
* This request does not have a User-Agent header - for diagnostic
purposes it would be much better if it identified itself (_all_
requests and responses generated by sipXecs services should
include either a User-Agent or Server header as appropriate).
