just as an idea: The Cisco's can be remote controlled via telnet. With 
the embedded browser you could start a script which initiates a call
with "/var/spool/asterisk/outgoing" (or also via telnet) and then 
connect to the called phone, turn on speaker and mute. B just has to press
mute to talk back or speaker to hangup.

I guess with some modifications (ability to telnet/execute scripts) you 
could turn app_dial into an app_ciscointercom.

Quick and (very) dirty, but it works...

I'll try to log an intercom connection from the Cisco IOS Telephony 
Services this weekend, but this package comes with it's
own load for the Phone, so i think it's not working on the sip load.


Greetings,

Christoph
