  Hey guys,

 Many apologies if im just being totally dense on this one, but I've 
 been going back and forth for a few days now, and given how new the 
 presence module is there doesn't seem to be huge amounts of 
 documentation on it.

 I'm attempting to get the PA module for the latest (as of a few days 
 ago) CVS to work. All other config bits in ser seem to work fine. I 
 think perhaps my confusion is also about how it's supposed to work! 
 Perhaps if I could ask some questions, people could fill in where they 
...
  know the answers, or point me to the right place.

 I had in my config:

 if (method=="SUBSCRIBE" || method=="PUBLISH") { # BEGIN
method==subscribe
...

 if (t_newtran()) {

 log(1,"PRESENCE: Change of state detected\n");

 handle_subscription("registrar");

 break;

 };

 };
 Hi Dave,

I updated modules/pa/README this morning to try to reduce confusion. 
There are two functions that need to be called: handle_subscription for 
incoming SUBSCRIBE messages and handle_publish for incoming PUBLISH.

if (method=="SUBSCRIBE") {
if (!t_newtran()) {
log(1, "newtran error\n");
sl_reply_error();
};
handle_subscription("registrar");
break;
};

if (method=="PUBLISH") {
if (!t_newtran()) {
log(1, "newtran error\n");
sl_reply_error();
};
handle_publish("registrar");
break;
};

The function pa_handle_registration is no longer used.

Presence aware UA's register in the same way as others. To update 
extended status on the PA, they should send PUBLISH messages to ser.

Thanks Jamey! 

This is a great help.. I was confused by all the exported functions.  So
do I understand that pa_handle_registration is still an exported
function but its deprecated now and is not needed?

If you have a moment to explain (or point me at the doc) about when the
db tables get populated... I never seem to see anything in them, so
would you mind giving me a few hints as to what tables I should see
getting populated on which events?

Many thanks for any help you can provide,

Dave
