asterisk users - Mar 2005 - Paging and Intercom using Sipura SPA-841

I want to implement a one way announcement  and paging facility  using 
Asterisk and Sipura  phones.  The wiki says  Sipura phones only support  
Auto  Answer using the  Call-Info  header which is no lone shipped with 
asterisk stable since 1.0.4.

I would like to ask if  anyone has implemented a similiar  facility 
using  Sipura  SPA-841 or any other  SIP phones. If I could take a look 
at how they have done this with a snippet of the extensions.conf I will 
be very grateful.

regards,

Kavit

Well, I'm using intercom with a couple SPA-841.  Currently using * CVS from
a couple weeks ago and a macro in extensions.conf.  It should give you some
idea:

[macro-intercom]
; ${ARG1} - Extension
  exten => s,1,SetCDRUserField(intercom)
  exten => s,2,SIPaddheader(Call-Info: \;answer-after=0)
  exten => s,3,Dial(${ARG1})
  exten => s,4,Congestion
  exten => s,104,Busy
