Quality of Service on BCM 50 VPN/ DSL 1

[TnPhoneguy]

I have a customer that has multiple locations and to cut costs he wants to install BCM 50s at all locations using VPN/DSL and get rid of his point to point T1s. I am a little leery of ding this. Anyone with experience with this setup?
Thanks

To me, it works fine, just got to make sure you implement QOS, establish a VPN between all locations, and make sure your data bandwidth is good.

Will a 3 meg dsl have enough band width?

I think that number is for only download, but it will depend if you actually get 3Mb up and down and what actually goes across that. Each conversation takes up 64Kbps up and down but you will still need a router that can handle quality of service.

You can be watching Youtube and your conversation will be choppy.

Keep clear of BCM 50a . Use BSR 222 or 252.

 

[TnPhoneguy]

what is BSR 222 or BSR 252

I dont think is 3MB for up maybe 3MB down 128 UP, if it is like that, is not enough for 10 telephone calling at the same time

G711 takes 64 kbps in each direction (actually higher than that due to IP overhead). G729 would use less but remember that perceived voice quality is worse on G729 versus G711 and deteriorates rapidly if there is any packet loss or jitter.
