[SR-Users] Handling quota/call limits - kamailio 1.5

[Graham Wooden]

I agree - I actually tried to use the dialog module, taken from an mailist
post back from Aug 2009,

 http://www.mail-archive.com/users@lists.kamailio.org/msg04127.html

But ran into issues implementing it.  With that, I will focus back on that.

Thanks Alex,
