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

[Chris Travers]

Hi all;

I have been searching for an answer to a question that a customer asked 
me and I have only found a few older answers.  So, wanting to find out 
if anyone has any experience with this issue and can help provide me 
with some advice.

I have a customer which is strongly interested in using Asterisk as a 
PBX.  One of the core requirements, however, is that the system MUST be 
able to support intercom/paging.  Having searched the archives, it 
appears that this question was asked about 6 months ago, and the answer 
was that the Cisco phones support this using SCCP and having one line 
set to auto-answer, but at the time this was not supported in the SIP 
image.  Is this still the case?

Although I know that SIP is the preferred protocol for connecting these 
phones with Asterisk, how stable/reliable are the skinny channels?  Is 
there any reason I should be rethinking this solution?

Best Wishes,
Chris Travers
