3com Solution

3com Solution

One of my colleagues has recommended a 3com solution but I have no idea of what I am looking for. I have some experience in other phone systems but know very little about 3com. Can someone tell me if it can have 300 extensions and if so can someone give me a budget price of what I should be aiming for so I do not get ripped off. I am in the UK. We are looking for 300 ip phones with voicemail and ISDN30



RE: 3com Solution

3Com make great Voice solutions, but a little more info is needed to make a suggestion on price...

Do you require SIP?
Single or Multi site?
Redundancy in Call Processor?

Your best bet is to find a 3Com certified reseller in your area to do a site assessment.

That being said... Here is an estimate on prices in USD...
300 3102 Phones ~$60,000
300 Group2 Licenses ~$25,000
V3001R Call processor ~$10,000 (with RAID and 2PSU)
Expansion Chassis and ISDN Card ~$4000
Voicemail upgrade ~$8000

All said, Hardware around ~$110,000.00
These prices are estimates based on what I have seen... It does not include volume discounts, install, etc...


RE: 3com Solution

I am looking for a multisite solution with 5 small sites and 1 centralised site. I would like to have some form of unified communications. I have seen that alot of the phone systems can interlink with outlook and determine if you are in a meeting etc.

There would be Sip requirements.
Redundancy would be ideal but again price might determine this requirement.
I would like some form of fallback for the small sites.


RE: 3com Solution

Well remote site survivability will require more hardware and more $$

Do you have SIP equipment that you want to integrate, or want to do SIP trunking? Otherwise, 3com's native protocol might work and save you money.
When upgrading to SIP on an NBX you can no longer use the integrated voicemail and require their IP Messaging server.

The VCX Line is SIP native, but is also more expensive.
The VCX Connect 100 is the base model which is around $5000 I believe with support to 25 phones and mailboxes. It also supports redundancy.

To have remote site survivability, you will need a Network Call Processor at each site.

There are many software packages to integrate with the 3com voice systems. It sounds like the 3com Presence Module would give you what you are looking for.

There are so many different options and ways to solve your needs that you should contact your local 3Com reseller to come onsite and give a demo of the equipment. Most should have demo systems that will give you a look and feel of the system.

The 3Com system is a great system and can do everything you want...

You can always post info on the quoted system for review...


RE: 3com Solution

Thanks again John

RE: 3com Solution

What platform does your servers run on?

Aswell as VCX Connect, VCX can also be ran on IBM's System X servers and also on System I.

If you have an existing System I then spare capacity can be utilized if there are enough resources.

VCX runs on Linux (it's a hardened red-hat kernel, aptly named vcx-linux.

You could run this on a virtualized platform or on a dedicated box.

Are you wanting to run 300 phones on a single ISDN 30? You need to take concurrent calls into consideration, and also the WAN links between sites.

3Com's VCX is fully backed by IBM.

RE: 3com Solution

I would definately go VCX over NBX....that is unless you are a Multicast Routing Expert.  Biggest flaw of the nbx in my opinion is its use of multicast.  Multicast are tough to manage in a WAN environment.

RE: 3com Solution

It does take special routers to handle the multicast, for remote offices on the NBX but it is not that difficult to manage. The router needs to support Multicast routing and PIM DM.

easy cheap setup, 2X 3036 routers ~450.00 each
Setup a GRE tunnel and encapsulate in IPSec.
And you could get away without IPSec, and just use GRE if you are not worried about security...
You just need the high encryption firmware.

Takes me about 15 minutes to setup the 2 routers for GRE or GRE/IPSec.

RE: 3com Solution

That sounds interesting engjohn.

Do you have any links to documentation for that? Because that could be very handy in my job!

RE: 3com Solution

Below is a working config for one of my setups. The IP address on the tunnel does not need to be real ( LA - remote) it is used by the tunnel to forward traffic.
