Future of IP Telephony: Smarter, Not Just Cheaper

By Brian Caulfield, April 6, 1998

Advocates of IP telephony at the Voice on the Net conference in San Jose
last week offered many visions of where they see the technology headed.

Imagine a phone service that can translate English into Japanese. How about
one that can make you sound like a movie star? Or another that can tell you
when your friends are on the phone? "It has to be the applications that drive
IP telephony. If it's just about transport, it's not compelling," said Francois de
Repentigny, an analyst with Frost & Sullivan, a Mountain View, Calif.,
research firm.

IP telephony will have to do more than provide low-cost phone service,
because the low prices may not last forever, observers said. [See "IP
Telephony Sees Price Wars."]

"Someone has to pay for the infrastructure," said de Repentigny.

Joe Rinde, director of switched network architecture at MCI, said that with
increasing amounts of bandwidth being brought into the home, phone calls
made over the IP network will eventually be made with CD-quality sound.

Rinde said the future of IP telephony lies with the ability to develop better
quality and functionality than conventional telephony. For example, he said, IP
telephony will allow businesses to replace Private Branch eXchange (PBX)
telephone switching systems with PC-based software.

"When your PBX system sits on a PC platform, the costs will plummet, and
developers will come up with APIs that allow much more functionality at a
lower cost," Rinde said. "Imagine being able to program your PBX box
through a Web interface."


Eric Sumner, group ventures vice president in the Switching and Access
Systems Group at Lucent Technologies, said IP telephony vendors could one
day offer voice modification, telephone buddy lists, and even, perhaps,
on-the-fly language translation.

But some said the hype is a long way from reality.

"The maturity of an industry is inversely proportional to the amount of hype
that is in vogue in those industries," said John Peters, general manager and
executive vice president of network services at Concentric Network, a
business ISP in Cupertino, Calif. "We've got a long way to go before we turn
this into a real business."

IP Telephony Sees Price Wars

By Andrew Marlatt, April 6, 1998

Voice-over-Net question is no longer how, but how much to pay

In a trend reminiscent of online brokerage commission wars, Internet
telephony service providers (ITSPs) are bidding down their prices in hopes of
luring consumers away from standard telcos.

I-Link Inc. earlier this month unveiled a 4.9-cents-a-minute rate for calls
between six major metropolitan areas in the West. The rate bests IDT's
5-cent rate and Qwest Communications' 7.5-cent charge. IDT and Qwest,
however, offer larger calling areas.

The rate reduction was one of a series of announcements made earlier this
month, including a deal linking Yahoo's white pages directory with IDT's
Net2Phone service, and the release of a study by Forrester Research
estimating that long-distance Internet telephony service revenues will grow
from $30 million in 1998 to $1 billion by the year 2002 [see chart, right].
Despite the industry interest, however, analysts don't expect consumers to
abandon the telcos en masse. Sound quality and ease-of-use still give
traditional telephony providers the edge for now.

Lower rates and lower quality may differentiate IP telephony from traditional
service, but the businesses do share a common feature: confusing pricing
structures. For instance, I-Link's 4.9-cent rate is available to subscribers
whose calls originate and terminate in calling areas connected to I-Link's IP
network. Calls outside the network are 6.9 cents a minute.

But both the penny price wars and disparate pricing schedules could soon
become a thing of the past. Forrester Research analyst Chris Mines forecasts
that sometime this year, an ITSP will introduce unlimited voice for a flat
monthly fee, similar to ISPs. How low those flat fees are will depend in part
on the regulatory environment, he said.


The current lack of FCC regulation is a large reason why IP telephony is
cheaper than traditional service. Currently, telcos must pay access fees to
local carriers both where the call originates and ends, whereas the FCC does
not require ITSPs to pay those fees. Analysts expect that to change, though
not this year. When that happens, said Mines, "One school of thought says,
'It's all over for IP telephony, because a regulatory end-run creates their price
and cost advantage.' We disagree. There are fundamental technical
underpinnings to cost and price advantages that ITSPs would have, and those
would persist beyond the end of regulatory disparity."

The technical advantages of a packet-based IP network include the ability to
support several conversations on one line, unlike standard phone lines, which
can host only a single conversation, said Mines. But the Internet protocol also
has drawbacks, particularly in compression. While voice over a proprietary IP
network is "at least equal to a circuit-switched network" because it avoids the
public Internet, "most voice-over-the-Net [VON] providers compress data,
thus introducing delay and lost conversation fragments," said Carl Boeing, an
analyst at Atlantic ATM.

While hardware vendors like Cisco Systems and Bay Networks are working
on gateway products to improve quality over disparate networks, VON is
already attractive in international markets, where traditional sound quality is
typically lower than the U.S. phone system. Companies such as Delta Three
have focused on international calling, offering PC-to-phone service at 12.5
cents per minute. This branch of IP telephony is the biggest threat to traditional
telcos, which make huge profits on international calls, said Forrester's Mines.

Blurred Boundaries

Some telcos are responding with their own IP initiatives. AT&T, for instance,
plans to unveil WorldNet Voice in the second quarter of this year, offering
fees of 7.5 to 9 cents per minute from selected cities.


ITSPs, meanwhile, are fighting to make their names as synonymous with
phone service as the RBOCs'. IDT's announcement that its Net2Phone will be
available on Yahoo's People Search white pages directory, allowing Yahoo
users to instantly place calls from their PCs, brings IP telephony "into the
mainstream," said IDT senior vice president of business development Jonathan
Reich. "It's probably the first such event that's brought it to the consumer at
large," he said.

Forrester's Mines, however, labeled the deal a sideshow. "Using your PC as
your primary voice communications device? I don't see that as a big,
mainstream marketplace," Mines said. Instead, he believes calls placed
phone-to-phone over an IP backbone will constitute the larger slice of the pie.

But when technology allows, the real power of Internet telephony will be
found in its multimedia capabilities, said Atlantic ATM's Boeing. "If you
subscribe to a local exchange carrier and place calls over a copper wire pair,
it's very difficult to obtain integrated services like videoconferencing and
video-on-demand," he said. "With this technology and the Internet's potential
as a communications entity, these applications are rapidly becoming a reality."

Such extended services may help ITSPs enter the business market, an area
they have pretty much left alone. Consumers, who pay an average of 20 cents
a minute for long distance service, are seen as a larger immediate market than
corporations, which often pay only 7 to 8 cents a minute already. But the
ability to turn intranets into low-cost phone systems may give businesses an
incentive to look at IP telephony.

"That business has not taken off," said Mines, "but it seems like a no-brainer."

Lightwave Extra! 4/98 Report on SONET, SDH & ATM
[Many excellent articles at the following site]

broadband-guide.com

Special Report, April 1998

SONET, SDH & ATM - Q&A

Question: Once viewed as potential competitors,
SONET/SDH and ATM are now frequently seen as working
together to increase the efficiency of fiber-optic networks.
What's driving this change in philosophy?

Answer: It's generally a combination of practicality and market
forces. At one time, voice, data, and video services were often
carried on separate networks - frequently by different companies.
Then things began to change, particularly in the United States.
First, voice companies like the RBOCs - who were big fans of
SONET networking - decided to get in the data and video
delivery business, and they wanted to do so using their existing
SONET-based networks. Meanwhile, other kinds of companies
who were looking to expand their offerings, both in terms of
service variety and geographical coverage, realized that in many
cases it was better to use existing networks, most of which were
SONET based, than build brand new ones. So it became
advantageous to find some way of melding SONET and ATM.
And SONET has proven amazingly flexible in terms of the
payloads it can carry. ATM payloads are just one example -
SONET is also proving capable of carrying IP payloads. In fact,
the battle to watch won't be SONET versus ATM - it will be
ATM versus IP.


Q: What are some examples of SONET and IP working
together?

A: The best example right now is Sprint, which is installing Cisco's
Gigabit Switch Routers to boost the efficiency of its fiber-based
Internet transport network. GTE Internetworking also will use
Cisco routers in a similar fashion. Cisco explains this approach -
which it calls "Packet over SONET" - in an article in our April
issue. While Cisco is making the most noise in this area, you can
be sure its competitors aren't far behind. IP over SONET makes a
lot of sense for existing carriers who want to add Internet
provision to their service portfolio; these carriers should represent
a healthy market for IP over SONET routers. However, it will be
interesting to see how new carriers, such as Level 3
Communications, approach the design of their IP-centric
networks. Will they also opt for SONET or will they try some
other tack?

Q: Speaking of SONET's flexibility, I understand Microsoft
is implementing the technology in a new way.

A: Yes. You'd expect Bill Gates would do nothing in a small way,
and Microsoft's new corporate network in Redmond, WA, does
nothing to change this perception. The company is touting the
network as "the largest corporate ATM network in the world,
possibly riding over the largest private SONET backbone in the
world." Few companies other than Microsoft would need the
capacity afforded by OC-3 and OC-12 rings in their corporate
network these days (and a source at Microsoft said they'd have
installed OC-192 if they could have gotten it!). However,
bandwidth demands are increasing all the time, and while
Microsoft is undoubtedly a trailblazer in SONET-based ATM
enterprise networks, I wouldn't be surprised if other companies
followed a similar trail in the future. Again, you can read all about it
in our April issue.
