re: Enterprise VOIP: Not So Fast A few things to consider:

- IP sets are still more expensive than non-IP
- Generally you need LAN/WAN upgrade
- Determining the origin of 911 calls
- Lots of $$$ to power the sets through a power outage
- No killer apps

I guess for this year will settle for Frame to MPLS migration to keep busy...

re: Enterprise VOIP: Not So Fast Re post 11

IP sets may be low when you compare them to analog but most vendors are now selling a family of IP phones that range from 120.00 to around 1000.00 on the high end with additional modules. You can find essentially equivalent pricing between IP and digital at each level.

Agreed on corporate network upgrades but mostly on the WAN side of the equation. However, these networks are constantly being upgraded in support of faster speeds and better pricing from the vendors and the carriers.

I dont agree that it costs more to power the phones through an outage. If your building is on backup power and your ethernet switches are on the same power backup you are good to go. This is not anymore expensive from the projects we have worked on.

No Killer apps. I think this is an old argument. If a vendor is leveraging SIP and presence in their offering than there are applications that are of value to the enterprise. If not for all users certainly for a subset of those users specifically mobil users. Things like presence enabled networking and personal portals are of value to the mobil worker.

re: Enterprise VOIP: Not So Fast We're moving towards deploying VoIP enterprise-wide. I have to say that, in my mind at least, the single most critical piece is how the network handles QoS. Given that people expect a desk phone to sound a certain way you have two choices: convince them cell quality is the norm, or provide them with the quality. The second you pass VoIP across a segment without QoS you expose yourself to problems. Fortunately for me our network is end-to-end QoS friendly. I don't think it would be worthwhile to try this without the network we already have in place. I'm not saying we won't have *any* problems, just that there shouldn't be many.

Of course I'm dreading the day when my shiny new IP phone catches a bug. :-)

re: Enterprise VOIP: Not So Fast Agreed - Schtop, this market is not ready yet.

Vendors are also banging on about ROI as opposed to straight cost savings - a change in the Marketecture, methinks.

Power is an interesting one. 802.3af is getting there, and that's pretty key for Ethernet connected handsets and base stations. No idea how well PowerDsine's midplanes are selling - anyone know?

Handsets are a major per-user expense. That said, I have seen handsets kicking around at about 100 Euro this year from guys like Zultys, AYC Telecom and Geneva Telecom. I reckon the handset cost will come down over time.

Other stuff; some interesting figures from Canalys (Applicable to EMEA): CPE line shipments in Q3 last year were 70.7% hybrid, 25.9% Voice PBX and 3.4% IP. Growth rate for IP line shipments was, er, fantastic at 62.9% YOY, but it grew from 2.2% - a huge amount of b**ger all. IP is a small market, but itGÇÖs getting there. By far the largest at the moment is hybrid GÇô which is possibly why guys like Avaya and Mitel are doing pretty well in the UK at the mo. Hybrid grew 22.7% YOY Q302 according to the Cananlys figs.

What I am seeing from the integrator end of things is more resellers looking seriously at the technology as a future direction, and also as a means to persuade their customers to have a crack at sorting out their networks.

Last possibly interesting bit; the Telecoms Industry Association in the UK has done a bit of interop testing on systems from Alcatel, Cisco, Nortel and Avaya. The report on phase 1 is here:


and phase 2 - which will cover IP systems interop with DPNSS - is just about to start.

All signs that the market is getting there - but not as quickly as the vendors seem to make out it is.
