SIP in higher education

[Stephen Kingham <>]

Hi Dennis, et al

I have all the best intentions to attend these meeting, only I often 
choose to stay asleep instead due to the timezone change ;-).


Anyway I wanted to report that Quincy Wu and I gave a 1 day SIP Tutorial 
at the 19th APAN Meeting in Bangkok with 20 attendees, the SIP.edu 
project was a part of that.  It seamed well received and there is a lot 
of interest in SIP in APAN, much more that H.323.

For example Sri Lanka looks like a real possibility of sip.edu.


One major issue is how to route E.164 calls.  I know this is out of 
scope of sip.edu but please allow me to mention it here considering your 
success in sip.edu routing. 

Several APAN Members (I am one) are looking at
-ENUM
-TRIP
-as well as a hierarchy of SIP Redirectors with static entries as a 
short term solution.

In APAN H.323 and the E.164 routing using GDS has not taken off, but 
there looks like a real possibility we could get E.164 routing using SIP.


Please forgive me for raising E.164 routing here, I realise there are 
other appropriate mailing lists.

Regards

Stephen Kingham
