Dear
Readers,
September
2001 was a difficult and sad month. On behalf of the
VoiceXML Review's Publication Board, I extend our sincere
and heartfelt sympathy to the thousands of people directly
impacted by the recent terror attacks. We also commend
the selfless efforts of the thousands of rescue workers,
medical workers, volunteers, etc. who have responded
and continue to respond with remarkable fortitude and
compassion.
The
VoiceXML community has also reached out. For example,
several days after the attacks, I received an email
from a colleague describing a free voice service deployed
by Tellme (1-877-322-9438). With simple spoken commands,
callers can access information such as airport status,
travel briefings and security policies, from the FAA's
website. A simple application, but very useful for those
who were at the time stranded around the country and
trying to get home to their loved ones. As technologists,
many if not all of us often struggle with the potential
misuse of the technologies we create. While it should
be our constant goal to build and promote technologies
that can be applied to improve the lives of our neighbors,
it is particularly encouraging to see this occur spontaneously
in times of great need.
This month our focus is on server side technologies
that compliment VoiceXML. Eric
Burger's article The
Interface between Next-Generation Application Servers
and Media Servers: SIP and VoiceXML sheds light
on how the Session Initiation Protocol (SIP) will compliment
VoiceXML in next generation networks. Eric's article
provides a brief sketch of SIP, in terms of its origins
and purpose, and then goes on to establish its advantages
with respect to session management for VoiceXML applications.
For
those of you who come from the web development world
and have just recently gotten involved in VoiceXML,
all this talk about next generation networks, call control,
etc. might seem rather intimidating. To get your feet
wet, I'd recommend you read Rob
Marchand's First
Words column this month. Rob's column covers "call
control 101" this month as he goes over the basic
telephony support provided in VoiceXML 1.0.
In
the Speak
& Listen column this month, Jeff
Kunins responds to your questions on mixed-initiative
voice dialogues and the VoiceXML <link> tag. Jeff's
discussion of mixed-initiative is thorough and well
illustrated with sample code. Keep those questions coming:
speak.and.listen@voicexmlreview.org.
Sincerely,
