phone
testing - What is your school doing? (Asterisk)
Jose,
Indiana University has operated
a Call Manager system
similar to yours for several years. We are also working with Nortel on
SIP.
You make excellent points about Asterisk.
From my experience,
Asterisk is easy to install. Paul Mahler's book VoIP Telephony with Asterisk is
a good
starting point for those who want to implement it. In addition to
supporting virtually any VoIP protocol (SIP, H.323, etc) Asterisk
supports a
new protocol called IAX. IAX is great for traversing NATs and
firewalls.
In addition, end-points are very inexpensive. We bought some ethernet
phones for under $40. In fact, the entire system can be built for a
couple of thousand dollars (most of the cost is in providing a server
suitable
for MEPIS Linux).
As you mention, there are some great
opportunities to exploit the open
source architecture. Perhaps we could collaborate in this area,
through
ACUTA, other HE organizations, or directly among partnering
universities.
There are many opportunities for
internetworking, such as
Internet2’s SIP.edu project (DNS dialing; i.e. dial by e-mail address)
or
through, for example, the Global University Phone System: http://aboutreef.org/gups
which uses
E.164.
I expect that it is a matter of a few months
before organizations, such
as ACUTA, develop special interest groups (SIG) or birds of a feather
(BOF) (or
whatever you call it) to focus specifically on Asterisk. Asterisk is
really exciting, and I hope that everyone takes a serious look at it.
Thanks for introducing this subject on the
list server.
Best regards,
-Mike Enyeart

Michele,
Colorado State University is
using a Cisco Call Manager
supporting 7960,
7910, 7905, 7902, 7935. However, we are
highly interested and are
testing the Asterisk open source SIP PBX. We
like its native support
for
analog telephones, ability to connect
multivendor SIP telephones, and
its open source architecture. In fact, we
have a development project to
construct a "production" voice mail server
based on the
native Asterisk
voice mail system. We are in the test stage
of that service.
We are also interest in ascertaining whether
other institutions are
interested in the Asterisk.
Regards,
Jose Valdes
