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?
Apparently your search didn't find several other postings on the subject.
The cisco v6.x sip releases also include the ability to "auto-answer" a
call (required for phone paging), however some folks tend to suggest that
is a security problem as anyone can call that autoanswer extn number
and listen in on whatever is going on around the phone. There is no
beep or other indication the phone/microphone is open.
Thanks. Given HIPAA, I am not sure I would want to rely on a light,
beep, etc. since these might not be noticed until it is too late. My
solutions is actually very simple-- only give certain extensions access
to the intercom extensions. Others are not allowed to do this. Period.
Best Wishes.
