Subject: Re: [jdev] using XMPP for discovery of SIP addresses

I'm the author of a package called Shtoom, a VoIP software suite
written in Python (using Twisted). I'm thinking about adding Jabber
support to Shtoom for the purposes of discovering someone else's SIP address (thus avoiding the need for a SIP registration server,
plus people can use their existing Jabber accounts rather than having
to create a new identity). I'm at something of a loss as to how to
do this - should Shtoom publish the SIP address, or should it instead
ask another XMPP client "I want to make a SIP call", and it can then
decide to send back the SIP address. I've not been able to find existing
work in this area - TINS looks interesting, but it's not really what I'm looking for right now.
Cool.

I have a few questions for you:

1. When a user wants to discover a contact's SIP address, do you assume
  that the user and the contact already know each other? If so, they
might already be subscribed to each other's presence, in which case it seems reasonable to use the reachability address proposal I have
  started working on:

  http://www.jabber.org/jeps/inbox/reach.html

2. Or, are you thinking this will be a more generalized service, which
  enables a Jabber user to discover any other user's SIP address? In
  that case, it might make sense to put your SIP address (and any other
  VoIP address) in your vCard (or vCard replacement!) and/or build a
  better kind of user directory service than what we have now.
