Solutions for Small Business VoIP?
MajorBlunder asks: "I'm part of the IT department of a small but prospering software company. We have recently filled the capacity of the POTS PBX phone system we currently have installed. We are currently looking into switching over to a VoIP phone system. We have a sizable IT staff in proportion to the rest of the company, so we'd like to be able to maintain the hardware/software in house as much as possible. I wanted to ask the Slashdot readership what experiences they have had with switching over to from POTS to VoIP. Any recomendations for full end to end solutions would be appreciated, and recomendations of things to avoid would be great."
I work for a small firm, 100 people or so across 3 offices which are relatively close, about to add another 20-40 people. We are in a similiar position, because our old PBX system won't handle that many users without some upgrades, which we don't want to do because it is reaching the end of its lifecycle. We did a little looking around, and suprisingly the Cisco Call Manager Express was the best priced solution for us. The only way we could beat their price was going with an IP PBX system instead of a VOIP solution. They were running a promo, so there was a 39% discount from the list price on all hardware. Unfortunately, the owners decided to hold off on the upgrade and bandaid our system until late next year because we will be moving into a new building and merging two of the offices. We couldn't get a quote from Avaya, their rep never called us back, and both 3com dealers we spoke with had recently quit selling 3com. I can tell you not to go with Nortel, their solution was over 1.5x that of the Cisco solution.
The cool thing about these phones is each phone gets its own real phone number as well as internal extension. We are located in California and when we have trade shows in Florida we take one of these phones and plug it into any ethernet jack. The phone auto-configures itself and you get the same phone number and extension and you can call other people in the office on speaker as if you were in the next cubicle. Pretty rad. Hope this helps.
I've switched to using http://asterisk.org/ along with http://www.broadvoice.com/rates_compare.html. I think you'll find this Wiki to be a very useful resource: http://voip-info.org/
g ory&category=hardware or any other Analog Telephone Adapter (ATA), or you could use Softphones installed on employee PCs such as X-Lite (free), or similar.
The plan I'm using is BYOD-Lite which costs me only $6 a month and there was no activation fee, since I had my own VOIP equipment in the form of an Asterisk PBX installed on Linux. From what I can tell, they are one of the few providers who allow the use of customer supplied VoIP hardware/software, in my case Asterisk.
Something you'll have to research is what technology you want to use for hooking up individual phones to Asterisk. One possibility would be to use hardware from Digium: http://www.digium.com/index.php?menu=product_cate
Good Luck!

last three years. We now have over 250 phones installed at 4 locations(including a call center). We started switching to Asterisk three years ago and grew the system to the point where everythign is Asterisk and we do all inter-office calls over VOIP(IAX trunks). The cost savings in licensing costs alone more than justifies 2 full-time IT staffers salaries.

If you have some time to get comfortable with it, you will be very happy with the control you have over the system and the tremendous choice in phone hardware you can use with Asterisk. And if your company is anything like ours, they will love the cost savings.
Here's a link to a case study presentation I gave at Astricon 2005 last month:

What is the deal? All you have to do is link asterisk.org and you get modded up 4 informative? geeze, is that sarcasm in the mods???

OK REAL Voip in a nutshell. You can run voip INTRAoffice then go out to copper (PRI) yourself or you can find someone to do voip trunking. (ie Your voice travels to an offsite virtual PBX and they send it to the pstn) [I say REAL voip because I'm talking business class, not running skype over a dsl line for kids to talk.]
While trunking is the coolest way to do it, sadly, voip trunking is about where cell phones were in the late 80's. Useable but you had to be sorta dedicated to the task. But I'll give you an example.
One of my clients decided to let speakeasy do the trunking. I (then) wholeheartedly recommended Speakeasy. It was a nightmare.
The problem was that we were like their third business VOIP customer. The bigger problem was that they lied to us and told us they knew what they were doing. I've been a full time geek almost 20 years. --I have NEVER had a customer support nightmare as bad as speakeasy VOIP.-- The problem was they had nobody trained on the system and they just made shit up. Then when you asked them to do what they said they could do, they would claim they never said it. I got to the point where I put EVERYTHING in writing.
If they had just come clean and said "Hey, we're learning this, give us a break" I would have helped them... But they didn't. I finally left my "dedicated" support person and went into the regular support queue. I got the support person to admit they were so new at it and they were clueless. I went back to my "dedicated" support person and told him the gig was up and he just stammered.
****But the service was good*****
The fact they were lying sacks of shit not withstanding, by the time they delivered the product, it worked well.
The topology goes like this.
You have a Edgemarc router (I think it is edgewaternetworks.com, google is your friend) and you put everyone behind it. (Voip phones, workstations and even servers)
The thing about the edgemark is that it does the traffic shaping to give priority to voice. (With speakeasy...) Every phone off hook costs you 90K. So a 1.544 T1 gives you 16 phones off hook simultainiously. (not 24) The balance is allocated dynamically to data. (Many systems use 64K per line) Speakeasy can bond 2 T's to give you 3MB if you need more lines.
Behind the Edgemark, you put a standard issue 100MB switch for your network. Spekaeasy uses (used) Cisco phones which have 2 enet ports. You can daisy chain as many phones as you like and the LAST one can be a phone or a PC. We often wire each branch phone-phone-phone-workstation.
With a SIP phone (google SIP if it is new to you) you can bring the phone anywhere in the world and plug it into a ethernet jack and you have your extension with you. No long distance etc. People just dial your local number and you can dial interoffice extensions just like usual. -coolness-
This is a big advantage of outsourcing the virtual PBX. (or setting yours up to support WAN connections.) Sadly, while this feature is possible with Speakeasy phones, (no exaggeration...) they didn't have anyone on staff smart enough to figure out how to do it. They lied to me on several occasions and said they knew how. (but no I'm not still bitter
With most trunking systems, each phone gets its own phone number (google "DID" it stands for 'Direct Inbound Dial' or some such) this is cool because they can bring their phones or use a softphone on a laptop.
Why Voip?
To me the biggest reasons to go VOIP today are to avoid the cost of a PBX or avoid the cost of long distance. Speakeasy charges about 26 bucks a month per line but since you use a virtual PBX running on their system, you have no out of pocket for the PBX. Good VOIP phones cost no more than good regular phones so that is a draw IF you are starting new or replacing equipment. But regular PBXs ain't cheap.
