We are looking for a VOIP provider.

Our needs are pretty basic but would prefer a more business centric provider than say vonage.

We just need at least 3 lines.

I have used Vonage and Skype (although Vonage is much more practical in a business environment). What makes you think Vonage is not suitable to your business requirements?

Try junctionnetworks or vonage

Check out: http://www.logincall.com and http://www.wishacall.com/

Ive used lingo and vonage. Currently using vonage.. No problems here.

I have used Teliax (http://www.teliax.com) for business services. Their service has been very reliable.

vonage seems just more consumer and only have 2 port options listed on vonage.com

we need atleast 3 ports for different lines.

Ive used lingo and vonage. Currently using vonage.. No problems here.

did you have problems with lingo or why did you leave them?

You can try voicetrading com (sorry still cannot adv links).
I was in contact with them long ago you can try them.

www.globalinx.com, we have a hosted PBX solution with 4 lines with a Cisco SPA942 phone.

You might check out Freedom IQ (http://freedomiq.mychoicevoice.com/). My roommate got one phone from them since he had a Freedom toll free number and he was very pleased with it. I got to test it out as well a little and the quality was fantastic. I know he relied on it quite a bit for a few months and he never complained. I am hoping that he will get another phone so I don't have to rely on Vonage.

Vonage is pretty good and I am pretty happy with them. But I really only use them now when I need to call friends in Mexico / Europe.

Here is one for you http://www.ringcentral.com

I'm currently using Vonage and have been happy with them but I just avoid listening to news about their financial situation. :D
