[Serusers] ser 0.9 config

Steve,
Here is my ser.cfg. If you find any potential problems or errors with it then please let me know.
The general setup here is ser-0.9 is the sip router, asterisk 1.0.1 is the voicemail server and we
use a third party for PSTN access.
Click-2-Dial is not handled with FIFO commands, but rather with sipp from sourceforge because this
lets us seperate the web console from the sip proxy. We do not use serweb, so we have our own web
frontend replacement for serweb.
This ser.cfg makes use of the avpops module for call forwarding features and some voice mail
stuff. The call forwarding stuff got rather complex because we had to make sure the number a user
keyed in to their call forwarding settings was "valid". For example, if they did not have
international dialing permissions then they wouldn't be allowed to have an international number in
their call forwarding settings. The other complex part for the call forwarding section is the fact
that you have to know in the reply_route which call forwarding number to use under different
conditions, (ie forward busy versus forward no answer).
The final note is that we have our own custom ser module called xdz_tools which exposes the
is_caller_blocked() and is_did_unassigned() functions.
The is_did_unassigned() function is needed so we can determine if a DID is assigned to our PRI but
not allocated to a subscriber. This prevents infinite loops between our SIP proxy and the PSTN
gateway.
The is_caller_blocked() function is used to determine if the callee has a line block on the
caller.
Hope this helps.
Regards,
Paul
