We had our new VoIP system but in end of last year, bulk of the kit was configured off-site by the contractor, were running a Cisco VoIP System.
All phones are PoE running on HP kit.
Do these systems support voice mail and sms type messaging?
Ours does yes - if u want to know who we used, PM me.

I probably will, just getting ideas before I present to SMT
Looking at implementing a MS Lync based system here
OCS here - moving to lync this year.
I'd say never underestimate the growth in a project like this - you may not need external dialling yet - but have a plan for adding it, cause eventually you'll be asked ;-)
We use a phone system here made by epygi, it was very cheap for what it does and has been very reliable. Took about half a day to get my head round setting it up, but it works very well now. We use it for external calls but could be used for just internal only. On the client side we use SNOM 300 handsets, they are pretty cheap, are POE and have an extra network socket on the back for a pc to plug into so you dont need extra sockets.
Now its setup its just a case of plug the phone in, it boots and downloads its config from the system and sets itself up. We also have 3 voip wifi phones which work brilliantly, even roaming between access points.
Apologies for dragging up an old thread, but I wondered if someone could answer a quick question to do with IP Phones and PoE. I've been informed that in some cases an 8 port PoE switch may not be able to power 8 phones because a phone takes up more power than, say, a WAP. If this is true, what should I be looking for to find out whether a HP Pro Curve E2520-24 PoE switch can handle 24 phones being attached? The other switches will most likely have half the number of phones compared to PoE ports, but the main office area has a lot of phones, and only a 2U gap in its cabinet...
I know the basics of the technology but that's about all. We're going to be
moving office soon and we're considering dumping our Nortel Meridian PBX
system and thinking about IP telephony.
Any links to reference material on setting up a medium sized (50 people)
VoIP system for internal phone system? Of course, it'll need to talk to the
existing external telephone network :-)
We're looking in to a new phone system too and am interested in Lync. The one question I have is how are people connecting to the outside world?
Are people using mainly a SIP Trunk provider, or using an ISDN30 Pri to SIP Gateway?
I still have a combination of ISDN30 and SIP trunking. Increasingly the ISDN30 is only being used for backup purposes though. If you have reliable Internet connectivity there's no reason to use POTS and be stuck with one phone provider.
I am about to plan the migration off out E1 and BRI ISDN, we can have SIP via redundant ADSL and leasedline and reduce cost too.
May keep 1 BRI at each site for full failover.
You need at least one POTS for to handle emergency 999 calls.
