[Info-tech] A eshte ky fundi i centralave telefonike, apo pershpejtim i imple mentimit te IPv6, apo te dyja dhe me teper

[besnik.grajqevci at bt.com]

Sot e mora kete raport interesant. 

Fakti qe te gjithe prodhuesit e centralave telefonike kane migru (me
saktesisht po migrojne) ne IP telefoni e konfirmon definitivisht vendosjen e
IP edhe ne sherbimet e zanit (Voice Services). Kjo tani jo vetem qe
pershpejton nevojen per implementimin e IPv6, cka eshte ngadalesu me
implementimin e NAT dhe rrjetezave (subnets), por edhe rikonfirmon rendesine
e qualitetit te sherbimeve (QoS).

PBX Vendors Sing New Tune

I'm coming off an intense - but great - week at BCR's VoiceCon2002
Conference. The crowd was large (2300+), active and involved, the sessions
were well received and the exhibit floor was jammed -
virtually all of the exhibitors have re-signed and are eager for
VoiceCon2003.
In the current economy, that kind of re-up rate has become rarer than a hot
high-tech IPO.

The buzz at VoiceCon, of course, was about IP telephony in general and
IP-PBXs in particular. And what was new was that there are no longer any
nay-sayers among the equipment vendors. None - and I mean NONE -- of the PBX
vendors have a next-gen, circuit-switched, TDM product in the pipeline. They
are all betting their futures - and their customers' - on packetized voice.

Now to be sure, if a customer either can't justify or adamantly resists
migrating off circuit switching, the "legacy" vendors - Alcatel, Avaya,
Intecom, Mitel, NEC, Nortel and Siemens - retain a circuit-switched option.
But the paths to a circuit-switched future are fewer and narrower than ever
before.

Case in point: Avaya, which used VoiceCon to announce new IP telephony
offerings - call control/processing software running on Linux-based servers,
new media gateways, management software and a new IP softphone. In
explaining the new products to me, Jorge Blanco, Avaya's director of
strategy and planning, showed one slide that I found particularly
fascinating -- a "decision matrix," with various migration scenarios leading
to Avaya's product offerings. What I found striking was that only one of the
six or so paths led to a Definity (read:  circuit switched) outcome; all the
rest take the customer to an IP telephony solution.

Similarly, Avaya recently released a White Paper entitled "IP LAN Telephony:
The Technology Migration Imperative." Imperative!  And it claims that with
these new products, the company's goal is to  "accelerate mass adoption of
IP telephony."

I usually try to ignore the marketing hype associated with new-product
announcements, but this represents a huge shift in market positioning.
Avaya, until recently, gave only the most grudging of acknowledgements to
packetized voice. It would sell you an IP-based voice system, but you had to
really want one. And Avaya's wasn't alone in this regard.

At VoiceCon, however, the world changed; Nortel, Siemens, NEC, Mitel,
Alcatel and the rest of the companies with roots in the PBX business all
began singing a new tune: The time is right for IP telephony. The guys from
Cisco may not be happy about the new level of competition, but they may find
comfort in knowing that the legacy PBX vendors have validated its view of
the future.

Of course, there are still some tough, unanswered questions: Have the
vendors changed their commission and bonus plans to emphasize the new
IP-based voice systems? Will the technicians who show up to service the new
systems have a clue? What about security, voice quality, traffic engineering
and system reliability?

And most importantly, how will customers respond? There's general agreement
that IP telephony is the sole bright spot in an otherwise grim PBX market.
Even so, IP shipments are expected to account for only around 5 percent of
the total stations shipped in 2001-2002. And as a percentage of the total
installed base, IP stations hardly register at all. But, the gauntlet has
been thrown: All of the PBX vendors are intent on proving their commitment
to convergence and to IP.

Over coffee towards the end of the show, my colleague Sandy Borthick and I
were discussing this new "reality," and Sandy came up with a historical
analogy that seemed reasonable: She said "think token
ring," which also had a huge and loyal installed base within the largest
enterprises in the world. But token ring and its star topology, was first
surrounded, then encapsulated and finally rendered irrelevant by Ethernet-
and TCP-IP-based solutions. Sandy wondered whether circuit-switched voice
was about to suffer the same fate.
