Found a few issues that may have been already known or fixed. I'm at revision 2230. Let me know if you'd want me to list these issues into separate posts. Here they are, FYI:
1. When you edit a customer from the admin portal, the customer's data comes up blank.
2. In a callback call, the first leg of the call does not show up in admin's CDR. Note that the CDR *does* show in the customer's area correctly. This skews admin's accounting and reporting numbers.
3. Found these logs flooding the syslog, so it may be worth going with PHP's recommendation of using date.timezone instead of date()?
Code:
Jul 28 11:31:07 php: /var/www/html/a2b/common/lib/Class.A2Billing.php[245]: date(): It is not safe to rely on the system's timezone settings. Please use the date.timezone setting, the TZ environment variable or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/New_York' for 'EDT/-4.0/DST' instead
4. The customer is not able to activate with the default settings sent through the email.
5. The "Add Payment To This Card" button in the admin's area does not work.
6. The notification area is a nice addition! The only messages I've seen in that area are with subject "No Message Unknown". Clicking on the individual messages does nothing but changes the "New" to a "cross sign" (Delete). I've never been able to read what each of those messages are about. I'm thinking that's a bug?
Besides that, most modules are working very nicely, so great work you guys! As always, if I find the fix to the issues above before you guys, I'll be more than happy to post my patch.
EDIT1 [2009/07/28]: Added 4, 5 and 6
