Hosted 3300 1

[TrunkMan]

Looking at using a mitel 3300 as a hosted voice solution for 60-70 sites each comprising of around 5-10 phones which will use a VPN back to 3300 controller. Are there any limitations that may restrict me in achieving this ?

physical 3300 controller or MiCD? Router to Router VPN what bandwidth to each site? I could go on and on........

Well, I know that there are alot of variables, but this is a startup company, and I am a 3300 engineer, so I i was thinking maybe an ISS with MCD and SIP with tenancy for sites. But been digging around with MiCD, and still reading about MiCD, hence the need for asking these questions. Router to Router VPN's or anything that is secure and low overhead. This is still in the concept/planning stagesm, so I would welcome your input.

MiCD has a high buy in. ISS with SIP and Teleworker would be my choice. No VPN to worry about. Teleworker also supports local streaming so phones at the remote office that might call each other don't use up bandwidth. You could use compression in the ISS for the Teleworker phones to decrease pipe requirements. We have done this and it works.

Yeah, Ive been over the MiCD EGL and decided to check pricing on the 2 software part numbers. A little too much to invest at an early stage. So maybe better to run an ISS with MCD. The teleworker mbg is a very good idea. Also read about it being used with MiCD so thought about using it as well. Did you experience any "gotcha's" in your deployment ? The MCD and MBG aspect is straight forward but what about Latency,Jitter,Delay,Loss ?

 

[SXWizard]

Only problem is with the internet access at the remote site. If tyeh have a low speed DSL there may be issues. Upload speed is usually the problem.

Could do speedtests before deploying on the client side. Any idea's of Bandwidth requirements. I think its like 80Kb per call G711 but what is it in G729 and also what about overhead ?

Go for a controller with a teleworker.
Or go for for a VPN.
I think a teleworker is much easier.


BAZINGA!

I'm not insane, my mother had me tested!

With ADSL 256/256kb you can make one call.
With SDSL 256/256kb you czn make two calls.

So keep inmind that ADSL upload also consumes download at the same time!
Think of 100kb for each call.

[bobcheese]

standard g711 call is about 92kbps on wire but when speaking to customers I always quote 100kbps.

 

[TrunkMan]

What about enabling compression on the mbg. How much bandwidth would that save me?

 

[bobcheese]

Have found this to be detrimental to the MBG server as it takes up alot of processor resource. Think it even mentions in the EG not to use server if you can compress via PBX.
