How are you SIP-ing?

@MikeSmithsBrain said in How are you SIP-ing?:
Does your company have 30+ users on-site and you're using SIP?
If so, what kind of access are you using? 3rd party Internet or a dedicated circuit from your SIP service provider? How's it working?
This topic came up in a recent podcast where, Fusion's sales engineer, gave many wise yet little-known tips on how to transition to SIP without a hitch.
This is a hotly debated topic within the industry so I'd like to hear from the source... IT Pro's that are actually deploying SIP today, in an office with more than 30 users.
I always recommend SIP over normal internet as a first choice unless I have reason to believe the line has other issues.

We pretty much only use SIP both internally and with customers. Didn't know there was a problem with 30+ users, we never run into network issues there. SIP works pretty well these days. Sure there is always someone having an issue, but likely they'd have it with ten users, too.

@scottalanmiller Agreed. Tolerance for an occasional voice glitch has to be there if going over public Internet. I think the debate is whether or not with 30+ users, the likelihood of issues increases relatively, which puts a heavier burden on IT support.

No doubt it increases, but the real question is does it increase per user? I doubt that it does, maybe it flatlines but I doubt that the per user management load would increase. It does not that I have seen, for sure.

We have SIP over internet and right around 40 users. We've not experienced any issues since making the switch a couple of years ago.

How much has your internet usage gone up because of it? Is it noticeable or negligible?

We certainly never notice the traffic. 40 users is a maximum theoretical usage of 4Mb/s in each direction. And that is only theory. Realistically you can't really get over about 1.8Mb/s and that's still with every single user on an external call all at the same time AND using g711 encoding.
In the real world, 40 users would not be expected to hit a peak of over 800Kb/s more likely with average being more like 80 - 200 Kb/s for normal businesses.
And if you encode to g726 or something that trims way down, quickly.

Negligible, though to be fair phones are our tertiary means of communication. Email and Google Messenger probably see the majority of traffic for communications.

We sell Carrier Services and usually size based more on the number of calls not the number of people. 30 simultaenous calls should be easy on any good (read: true business class) Internet circuit. @scottalanmiller has the bandwidth nailed on the head above. We di try and get users to get the best Upstream bandwidth which for cable modem installs around here is very difficult (Time Warner only offers 5Meg UP even in Business Class which is pathetic).
For our needs internally we needed well over 100 simultaneous call paths. We went with a dedicated circuit to a Rochester based cough carrier cough and a backup trunk over an Internet circuit. While bandwith has never been an issue lets just say I can't wait for the contract for the cough carrier to expire so that we can port and go to the Internet for our needs and dump them!
