Hello,
I have a few questions regarding VOIP and network devices. I have my own
opinion about this but I would also like to hear yours, so I can make bring
the best possible service to the customer.
The customer is a future government agency.
We decided that it would be easier to use VOIP then regular land lines,
however I need to assure best quality of service.
1. I do not plan to install an asterisk server locally beacuse of some
logistics, but to buy an asterisk or similar solution from one of the VOIP
providers on the market.
2. Since there are less then 50 employees, I will need only 1 network switch
and I would like to hear your opinion on which make and model are you
suggesting - to support and possibly enhanve VOIP (48 Port switch) - I would
stay away from Cisco if possible.
3. They will be connecting to the internet (at the beginning) with 2-4
ADSL/SDSL lines. I plan to set up a firewall with 2-4 WAN ports with Load
balancing and QOS such that one of the ADSL/SDSL's bandwidth is reserved for
VOIP packets. When not in use, other services can request that bandwidth.
What make and type of firewall appliance should I use - which would meet the
above requirements?
4. Bandwidth. There will be 24 users - possibly each of these with their own
DID. Beside this I may want to set up each of this users with a virtual
(local) number, so they have their own fax lines. There will be a need for a
digital receiptionist, VM, VM to E-mail, Fax to E-mail, Conferencing, CF,
CW, and CT, Possiblility of Call Center, 1-800 numbers, etc. How much
bandwitch do I have to calculate for 24 users, each let's say with 2 lines?
5. Any other requirements you can think of and are not listed here?
Thanks fro your help, and even if you know the answer for only one of these
questions, please E-mail me back. I will post a full list of the answers for
reference once I have them all.
Zoltan.
