I'm looking for recommendations for a company who might be able to provide
us with a VoIP-based phone system for a multi-site medium-sided company
(90 trunks, 250+ extensions at Head Office, between 6t/20x and 30t/100x
at 16 or so other branches).

We already use Lucent/Avaya Index across most sites, but with neither
tie-lines nor VoIP (yet). Asterisk would be an acceptable candidate
system.

(We have a decent IP network already in place. Some providers seem to
want to try and replace our entire IP network; this is not an option.)

Thanks,
Chris

I'm very much out of touch, but some Avaya equipment supported H.323
channels (with upgrades), you never know. You may be able to get boards
for your current hardware.

People on uk.telecom are generally more au fait with surch equipment.

Hi Chris,

I would be happy to have a chat with you about getting this system se
up. You can either drop me a line on 08700 271 336 or email michae
(at) kinitron.co.uk.

We supply exactly these kind of systems and are experienced wit
working with existing Avaya installations.

Many thanks,

Mik

If you're expecting the company who installs your VoIP system to support it
once it's installed, you don't want to be in a situation where they blame
your IP network for poor quality calls or reliability issues [for example],
and vice versa. Them doing what they need to do to your IP network would
hopefully preclude this. And probably make it just as expensive as a
proprietary phone system. Oh well, swings and roundabouts!

CISCO or NORTEL

Chris,

If you want a gradual migration to a Voip system might be worth
considering keeping the Lucent / Avaya phones you have and fitting
Citel Handset Gateways. No LAN upgrades, No re-training users, no
re-cabling to the desk. Works great with Asterisk.

We have had the Lucent Definity at work interfaced to the rest of the
company via a Nortel Succession VoIP link. We have also had some new
offices kitted out with Nortel CS1000 systems (~250 extensions) and use
them also to run a long-haul link to India. You really need to have QoS
support but the first link runs over a BT MPLS without QoS alongside the
WAN link with very few noticeable dropouts.
