I'm just setting up a new office and have installed virgin business broadband with their router. I've also got a 48 port switch coming tomorrow (Cisco SG200 50FP, for anyone who's interested!).

If I plug the router into the switch, do I just need to switch off DHCP on the router to allow the switch to control everything?

Is there anything specific I need to consider? Initially there'll be 6 of us using the broadband for VoIP and data, using PoE to power the phones and making sure the switch prioritises voice traffic.

I'm relatively IT literate but don't want to miss something obvious in the setup.

Thank you all, the answer seems pretty obvious now!

We're expanding hence going for a belt and braces switch for the job.

We're growing quickly and need room to expand. We'll likely be 20-25 by Q4 with additional devices (printers etc.).

You're right of course. If I'd had the time I'd have done exactly that. I've had a window of opportunity to move offices and had to react accordingly.

I got access to the property yesterday, we move in on Saturday and begin working from it on Monday. The ageing 48 port switch we inherited with the office doesn't do PoE (essential), and anything I buy now needs to cope with expansion later this year.

A lost day trading, by the phone team being unable to function, would cost us around £4k in lost profit. Not a lot by some standards, but enough to say spending £300 more than I needed to on a switch that's reasonably certain to be capable of what I need for the next 12 months, is not such a big deal in the grand scheme of things.

I appreciate to IT bods here it's a bit like the proverbial 17 year old in General Gassing asking if the Caterham R500 he's ordered has cruise control and can tow a horse box.

Thank you all very much for your help and if I create an IT disaster zone I'll be back to let you know and give myself 50 internet lashes.

It all works! Well, it would do, but for the Virgin router that's blocking the IP handsets from completing their initial setup...

On that note...

If I need to get one, can anyone recommend a router (preferably one where I can disable SIP ALG) suitable to work with voice and data traffic?

Done exactly this. Thanks for the help, crowing, moaning and visions of impending doom, cheered me right up, luvs!

All working beautifully, thank you peeps.

Got a pro coming out next week to optimise. Will get it in writing he's a full pro, not a semi literate one
