IMPORTANT:  IN-PERSON MEETING IN ATLANTA MARCH 24 8:30 AM-5:00 PM

Everyone please plan to arrive on Sunday the 23rd so that the meeting

could get started as early as possible (8:30 to be exact) on the 24th.

Samir said that he was not planning on coming to the meeting and asked

if a conferencing bridge could be set up at the meeting site.

*Discussion*

CGU's SIP client is scheduled to be released by end of January. It

authenticates using the native SIP authentication (HTTP Digest using MD5

hashing). It is commObject enabled, has support for directory lookups,

and is completely customizable (URI of proxy server can be changed,

etc.). It is also "web-enabled", in that one can click on a sip URI link

and the application will open.

Alisa Haggard (UNC) will convert the sipIdentity into the ITU-T format

and will be contacting the group regularly.

Tyler expressed concern that that when the OID format changes, the SIP

client

may not work properly. Nadim clarified that this would not be a

problem and that changing the OID format should have no effect on

the user agent.

The general flow for the H.323 client to be requested from RADVISION

using commObject was discussed. The endpoint will authenticate, perform

an LDAP lookup, and return a list of commObject accounts belonging to

the user. The user will then select one account from that list and the

endpoint will self-configure based on the information in that account.

The client then will register with the gatekeeper. Annex E and Annex D

encryption formats will be supported.  This client will be "web-enabled"

in a similar manner. It will also allow a search on users. It was

decided that Radvision would be asked to implement LDAP based

authentication as the other methods which use SAML assertions relied on

network components which were currently unimplmented.

Egon noted he will not need Tyler's extra router for testing and that he

has one to use. Jill wanted Egon to provide the group with the MCM

configuration after testing, for use in the cookbook.

Directory of Directories Search:

Tyler expressed concern about Java's performance; Aditya noted that Java

was widely used as a server side platform on production grade sites.

Both agreed it is possible to run compiled Java code.

The URL for the vnet homepage is http://metric.it.uab.edu/vnet/

[NOTE: Jason has added a web redirect http://videnet.webhop.org to

redirect to the Vnet website] There was some discussion of items to add

to the webpage/cookbook including, but not limited to, a description of

the endpoints, commObject documentation, CGU's SIP Client code, and the

directory lookup code.

Samir expressed interest in running  performance testing on the Testbed.

He was most interested in the impact encryption has on performance.

CGU would like to test the SIP client against the Microsoft RTC server.

Jason to set up the Microsoft RTC. UAB to announce in two weeks, a

timeframe by when the Microsoft RTC server will be up and running for

use in SIP client tests.

[AI] Jill to speak with Georgia Tech people to make sure that a room is

available, preferably w. videoconferncing capability or phone bridge

[AI] Jill and Tyler to complete MRD/PO to RADVISION

[AI] Samir to send note to group about what is to be tested in the

Testbed.

[AI] UAB to announce in two weeks, a timeframe by when the Microsoft RTC

server will be up and running for use in SIP client tests.
