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
