Presence and IntComm WG

[Candace Holman <>]

On behalf of the PIC working group I'd like to extend my thanks to 
Vaclav Kubart for his work on synchronizing the PIC-SER PA module with a 
current version of SER. 

As noted in the details of his email excepts below, Vaclav has issued a 
PIC-SER PA module that is partly incorporated with SER, so it can be 
used as a replacement for PIC-SER functionality.  We need to help this 
project along by testing as soon as possible and reporting any bugs that 
we find.

Here are the tentative plans we discussed on the conference call today.  
If you have some time in the next few weeks please help out!  (Reply to 
the list if you can help.)

- research how to install it on pals-dev for testing
- install on pals-dev
- document how to install it on other servers, update the README
- gather volunteers to install on their own systems
- gather pals-dev or self-installed volunteer testers
- publish results continually over the next one to two weeks

Thanks,
Candace

===========================================================

Please if you find a bug report it to our "bugzilla" 
(http://bugs.sip-router.org/secure/CreateIssue.jspa).

I will continue with RLS improvements and SER and PIC-SER join in next 
days. And documentation of course... :-)
