[Asterisk-Users] dialing application - newbie question

[w fm3]

I am thinking about a making a web based directory that dials a number with 
one click.

>From an overview picture does the below look like the correct way to go 
about it:

web app sends something like the below call file to asterisk

Action: Originate
Channel: SIP/1010
Context: demo
Exten: 1234
Priority: 1
Callerid: 1212

The main problem is the actual phone must be set to auto answer otherwise 
SIP/1010 would have to pickup  before the call is placed.

on Polycom this would be  done with the ALERT_INFO = ring-answer with a 
really short ring time - ALERT_INFO being passed to the phone via SetVar on 
the above.

on CISCO 79xx the only way to do it is setup a new line that autoanswers on 
the phone and configure each phone to do this manually. - Is this still 
correct?

Thanx for any input.

Walt.
