Rod,

I've made a very basic dialplan for an Asterisk for beginners
presentati on a seminar kind of event last year.

This are the config files involved:
-/etc/asterisk/
extensions.conf : the file
with the dialplan and the includings of other files that are part of
the dialplan
-/etc/asterisk/extensions.d/plaza_voiceprompts.conf : a quick and
dirty routine to record and listen to your own voiceprompts
-/etc/asterisk/
sip.conf :
the file with the sip entries for the different sip phones
- /etc/asterisk/
voicemail.conf : the
voicemail boxes for the different phones
This is not a ready to go dialplan but (if I haven't made too many
typos translating the stuff from Dutch to English) for practicing it
will do I think. This is the scene:

A company with 4 phones, one for the reception and one for each
department (registration, communication and finance) Each phone has it
own context that sets the permissions for making calls (only internal,
national, international). There is one phone number that can be
called and the caller wil enter a menu. If a department is chosen and
the phone isn't picked up after 10 seconds the reception phone will
ring. If the reception doesn't pick up the phone the call is
transfered to an external number and if this is picked up either the
caller can leave a message. There is one incoming number that is
routed into a menu so the caller can make a choice.

The IAX2 trunk is just a fake. You have to configure a SIP, IAX2 or
ZAP trunk to be able to make or receive phone calls and adjust the
incoming number and adjust the Dial() line to your own trunk.

The voiceprompt routine is just a quick ad dirty but very handsome
routine to record your own voiceprompts and listen to them. The idea
is that you use a numbered list of the voiceprompts and adjust the
routine to that list. The hard part is to make the voiceprompts that
are used by the routine itself ("enter the voiceprompt number" and
"press 1 to make a recordig or 2 to listen") . Number 07 is "press 1
for recording or 2 for listening" and number 08 is "please enter the
voieprompt number".

The recordings are saved in /var/lib/asterisk/sounds/plaza but you can
change it to any directory you like as long as it is available.


Don't panic if you don't understand all of it at once. This example
contains the most basic issues for making a dialplan:
- menu
- routing calls to phones
- routing calls to voicemail boxes
- number matching (routing calls based on the number dialed and/or the
cid of the one that makes an inbound call)
- including contexts
- including config files
- set permissions on a per phones base
- voicemail settings
- parking of a call (transfer a call to number 700, you hear a number
(f.i. 701) and you can call or shout to a co-worker that a call is
parked on 701, he/she
calls 701 and takes over the call) for the settings see /etc/
asterisk/features.conf



There is much more to do and to learn but if you understand this
example I'm sure you will be able to make a very neat dialplan for
yourself. Succes!
