G650 or G450

[Montero84]

Hello!

What is recommended and easiest to install/configure for a location with 300 users... a G650 carrier or a G450 media gateway with CM 5.2 / CMM? We would like to do the installation/configuration by ourselves and have the vendor involved as little as possible or not at all. Thanks in advance!

I forgot to mention we would like to have LSP and a S8800 Server or double S8800. Please advise!

Well, for what I have been researching the G650 is going away anyways and it is no longer cost effective. make sense.

I have yet to find an official notice of end of sale for the G650. If you have found one, please post the link.

But there is additional information that one would need before making a choice. How many digital set, if any, how many T-1 lines, etc.?

AVAYA may never "end of life" the G650, but support for it is dwindling. In CM6, the dedicated "Control Networks" are no longer supported (so you must put the IPSIs on the customers LAN), there is a very big hint.

Also, for a new switch, ,it is not cost effective, and they are increasing the pricing on the IPSI's and MEDPRO's to make it even less cost effective.

Only if you have an old switch, with a LARGE # of digital phones, and/or DS1's (they better be TN464's though), would it even be worth considering a G650.

We mostly sell G430's w/EM200's these days, with mostly S8300D's
everyone buys IP phones and POE switches for "green space"

For your size (300 users) Media Gateways are the way to go
best to go IP phones

Maximum IP Telephones: 450 (w/S8300 Server); 2400 (w/S8500 Server)Busy Hour Call Completions: 10,000Maximum
G450s per S8500/S87XX/S8800 Server: 250Maximum
G450s per S8300 Server: 50

How do you make a G450 environment critically reliable? The G650's can be designed that way via PN's with dual cards in each even though it's very costly. I have 2 s8730's with 5 PN's and each has 2 IPSI, 2 Medpro, 2 CLAN. I'd be curious how to do something similar in the G450 design.

Well, if you look at the G450 it has duel network connections. For critical reliability ensure that they are set to fail-over to one another and ensure that they are connected to separate data switches. In our call centre or back office environments we install a minimum of 2 G450s, if the site calls for more we engineer it so that N+1 G450s are installed, all with redundant power supplies getting power from separate sources, we install 4 80 port chips, the system only uses 3 for a total of 240 time slots and a spare incase one fails.

You cannot get much further redundancy than that.

Still sounds like the G650 model offers just a bit more in reliability/redundancy.
