That depends a lot on your particular setup, Nick. If you're doing a pre-pay
by the minute scheme, there's no way for SER to cut off a call when someone
runs out of minutes, so you'd want to forward calls through something like
Asterisk B2BUA. If you're doing a monthly scheme, you can set flags based on
database values and SER is perfectly capable of shunting the calls to a PSTN
provider.
Some people will also use Asterisk to transcode (convert from one codec to
another) from a common VoIP codec to one that their PSTN gateway understands.
It can be done a lot of different ways. :)

When using Asterisk and SER together, should SER place
calls to the
PSTN, and Asterisk only deal with "special features" such as
voicemail, queues, autoattendants, etc? Or should SER be used ONLY
as a proxy/registrar, and all calls be routed to Asterisk so that
Asterisk places the calls to the PSTN?
Cheers!
