[Asterisk-Users] Service Unavailble, Sipura 3000, CheckGroup, what the heck??

Its almost impossible to respond to the above since the spa3k can be
configured in lots of different ways, and can interact with * in lots
of different ways. Since Sipura does not provide a nice way to post
their configs, it makes it even more difficult.

Personally, I've been using a spa3k with * for about nine months, and
really haven't had any problems with it.
