This particular work is in combination with OpenBTS, and they are terrible about user names. I basically need as much flexibility as possible, because the SMSC/BTS/HLR are all likely to tell me exactly what user names they're willing to accept. Considering it's likely I'm going to have to work with existing HLRs... you see the problem. Thanks for the direction! That will speed this process up significantly. There are a bunch of us using freeswitch here at Berkeley. Awaaz.de (http://awaaz.de/) for instance, is helping hundreds of farmers in rural India right now. I'd love to come out for cluecon, buy you a beer, and argue in person. We'll see if my advisor is willing to pay for such a trip!

I think the missing point is that you are terminating point for the user so the foo+1234 *is* what people use as the user name when talking to the system. Whatever you clearly are not interested in that......
You basically want to modify every channel to fire an event when it gets an inbound chat message so anybody can subscribe to them. SWITCH_EVENT_MESSAGE is already used for something you will need SWITCH_EVENT_RECV_MESSAGE
similar to mod_dptools.c 3260
and put it at sofia_presence.c 2921 inside the else
this really should be wrapped into a profile param to enable it so it's not firing all these events unless someone really wants it to. see endless config options being parsed in config_sofia and reconfig_sofia that set profile flags......
Now tell all your friends at Berkeley to come to ClueCon this year and we'll see about a student discount!

Let me repeat myself: the changes I am proposing will be backwards compatible. Nothing will be broken.
The dialplan abstraction is tangential to this whole discussion. I can build a mod foo which runs the dialplan, and have all messages routed to it via the + mechanism. This will probably be my initial version of the system. I understand the work you put into this, and that your decisions were well-reasoned for the use cases you envisioned (e.g., conference calls), but the abstraction isn't working for me. This system is just a piece, interoperating with a variety of other systems. Attaching a specific module tag, used by just one piece of one program, to a username in use throughout the entire system is not an elegant solution. This means I have to put a proxy in front of FS, adding this + tag to every message coming in.
I'm here and open to any solutions you might have to make the existing solution work for me. Fundamentally, I can't just shove a +tag onto every incoming message in any elegant way, so far as I know. I think that means this entire line of reasoning is just broken for me. Don't get me wrong here, I would be really really happy if I didn't have to touch sofia to solve this, it's really hard to grok. It's also a lot less work for me.
So far, I've proposed one alternate method for doing this. I want sofia to generate events and not route messages itself. Then I can listen to these perform whatever actions I need to. This may not work, and I'm open to implementing any other architectural changes you think would enable my use case. You're clearly the guy who knows what to do, and your advice is invaluable.

you control the user names on your system the prefix+ string is just part of the username people would talk to.
for instance ext+ namespace is has auto presence built in so if you add ext+1000 to your list it will auto advertise that it's online.
conf+ goes to the conference.
conf+888@server.com will go to FS on server.com and route the chat messages to the mod_conference.
so basically you are proposing to try to modify sofia and break the other stuff because you do not like the prefix string on the user names but its designed to allow you to cross connect protocols, eg mod_sofia has sip+ registered and mod_dingaling has jingle+ so you can use jabber to pass sip+user@domain.com to your buddy list and have it report accurate presence.
Basically you make a new module called mod_foo and register the foo namespace. Then on your clients you subscribe to foo+1000@server.com for instance. Chat messages to that foo namespace will arrive in your code and you have the option to reply to them completely agnostic of the protocol sip, jabber etc.
You seem to be asking for advice but then ignoring it coming from the author of all of the above who spent many man hours solving this problem so it would be abstract. so I'm lost for what else to tell you.
Maybe we can confirm that you are simply taken aback by the idea of starting all your usernames with foo+ and simply propose to unravel everything in pursuit of removing it?

Nope, normal SIP MESSAGE events, no invites.
I just need an easy place where an app can look up some variables in the directory, check presence information, and start a call based on an incoming chat event. I also need a system that interops with existing SIP chat services. I don't think the +routing does these for me.

Are we talking about that ridiculous new chat concept in SIP where it uses INVITES and dialogs?

I think I understand it. Basically, a client can prepend a +code that causes the message to be routed to a specific module. I don't think that fulfills my requirements. This is fine for basic routing, but it's not a very good programmable environment for chat applications, unless I'm missing something, which is always possible.
If I am, can you direct me to anything that explains it in a little more depth than your email?
