Bandwidth required for remote site

Bandwidth required for remote site

Bandwidth required for remote site

(OP)
Hi all.
I have a remote site connecting 15 x 6910 phones to MIVB9. The WAN link is SHDSL with a bandwidth of 512k. The phones frequently display "Contacting Server" and calls drop. The site also has PCs connected. How do I determine the correct bandwidth required?
Thank you.

RE: Bandwidth required for remote site

As a rule of thumb, each phone requires 100K per active call. 512K for Phones an PC is wholly inadequate.

Even if you consider compressing voice I doubt the Bandwidth is sufficient just for PC usage.

RE: Bandwidth required for remote site

I suppose the SHDSL isnt't a leased/dedicated line.
You always could try to setup QOS.

MITEL docs suggest different settings, going from CS3 (DSCP 24) to AF41 (DSCP 34) and EF (DSCP 46)
But I suppose it couldm't harm much to set it to EF.
On the router on the remote site
Source: remote voice vlan
Destination: mivb server(s), and to your mbg(s)
DSCP 46, EF

RE: Bandwidth required for remote site

Kw, I suppose they have a very expensive MPLS WAN infrastructure, small sites .5 Mb, big sites 32MB; that's what we had in Europe a couple of years back with BT.

At the other hand: 16 phone: I suppose 1 or 2 are calling, so the bandwidth should be enough.

Tinos,
Do you have teleworker licenses?
If my approach is not possible, or too expensive, maybe a separate cheap internet line for the phones only is an option?

RE: Bandwidth required for remote site

Bandwidth is the issue there mate as everyone else has said.
