[Asterisk-Users] Cisco 7940 Phones as paging system?

[Joe Antkowiak]

I am currently using 7960's with *, and line 6 is set to auto answer.  Works
great, customer is happy.  As far as an intro-tone, you can set the dial
command to play a sound (using the announce option) before the call is
connected.  I grabbed a simple tone wav file, and made it play that.  Now,
when the intercom ext is called, it plays the tone on the destination phone,
and wa-la, intercom

So it works.  Let me know if you need sample configs.

Dunno about Cisco, but wanted to let you know that the recent Grandstream 
firmware (.55 and later) now also has an auto-answer option. Still I 
guess I should mention that the microphone of the GS phones in 
speakerphone mode is far from a brilliant implementation (-> echo for the 
remote speaker talker, and too thin sound from the person in the room).

Cheers, Philipp
