Verizon DSL is the worst around here because (I agree) DSL should not be used for business. I've seen roadrunner go down to 25 kbps upload for very short periods of time. I know this sounds crazy, but the speedtests confirm it. There have been a lot more than one call where I get sent in to confirm the internet connection is bad and the ATA is fine. It pays well at least and the work is easy.... tell ISP tech support to send a line man or boost the voltage.

Sounds like you have a VPN figured out. I've not worked with comcast too much so really can't comment on them.

When bandwidth goes down (usually the uplink) we always see the transmitting voip only broadcasting every third or fourth word. The result is choppy audio to say the least.

I'm curious... What device are you using for 8 lines? Or is it multiple ATAs? I'd heard there were a few newer ones coming out at a reasonable price, but haven't played with them yet.... I'm daisy chaining the 4 port jobbies still.

just 4 plain verizon biz lines for 800 traffic and 4 mitel exts (presence of 8 local verizon hotel trunk lines)you hit auto attendant and get handed off to reservations off season during the day...then on the panasonic side there is a 4 ext ip card that is plugged into a multitech routefinder 820 and it is the only thing on a comcast static biz class broadband connection. and there are 3 ip phones and a softphone running off of the host.

doing networking between multiple systems i would deffinatly recommend a mpls curcuit for the quality of service guarantee i have systems linked with mpls and have no issues have alot of issues with dsl or comcast at other sites if you do use dsl or comcast make sure to get customer to sign off that you are not responsible for network issues because you wil deffinatly have them just my experience.

thats a given softail.

OK The sites do have 1.5M up\3M down and do not have a Qos guarantee. Is this something that other ISP providers are offering? or is it a special circuit from the CO? Our problem is that we deal with Telco CoOp's at one end and Qwest at the other. The broadband cable company is the only common carrier at both locations
