Hi all,

We are planning to replace our old PBX with a new VOIP system.  We have been using Lync for IM and presence, and really love it.  We are looking for phone system & desk phone setups that can be integrated into Lync to show when we're on the phone, and transfer calls.

We have about 12 staff that are split into 3 support groups (could be hunt groups), with some crossover (staff members in multiple) plus about 10 other staff members.  2 work from home in another city, so we would need them to have desk phones (so they can call without needing to be logged on to Lync on their pc) that can communicate securely without opening us up to SIP attacks.

The options I'm looking at for the phone system are either going Lync all the way, or finding a way to integrate Lync presence with the phones and phone system we buy

If we do go for a separate phone system I’ve been looking at either 3CX or snom.  Does anyone know why it seems so common to run snom phones on 3CX rather than snom ONE?  Am I right in thinking the snom ONE phone system can basically only use snom phones

I've been reading up on snom phones (seem to integrate nicely with Lync, but don't have the number of transfer/extension monitoring buttons we'd be wanting without getting the 42 button extension panel which is overkill) or Cisco SPA509g phones (good number of buttons, but don't know if they can integrate into Lync).

There are a couple of things that seem to be making the decision hard for me:
  • We want to have the system mirrored or a redundant copy in another data centre so if our main office goes offline we can click a few buttons (i.e. restore a backup configuration file and maybe change an IP address or 2) and be up and running.
  • Securely connecting the out of town users.
  • Staff working from home or elsewhere in the event of another quake taking out our office would need software phones (or just good old Lync)
If anyone has any suggestions I’d appreciate hearing them.  Or if there are any readers that have done some Lync integration I’d love to get any tips or recommendations you may have.

Aah, yes I've spent many hours absorbing information from that site and related links. Good stuff, but there's nothing like hearing from someone who's done it first-hand, especially locally.

I liked his comparison of the features (present and missing) between 3CX and snom, but I'm still finding it hard to work out why people don't just use snom ONE for the system in the first place.

go lync all the way! and grap a sip trunk while you're at it from callplus, orcon, worldxchange or others.

can also do hosted lync too - try microsoft office 365, or for a local option with sip trunks ready to go.

the snom phones are not bad, but the new purpose-built lync phones are a better integrated experience, and arent too expensive either. either way, you can simply plug one in to any internet connection, sign in on the phone, and make a call via lync.

there are also other options, such as grabbing a panasonic pbx, throwing software from CyTrack over the top and using their Lync integration to tie it all together.

all the Lync phone connections use SIP TLS, so are inherently secure - unlike UDP sip endpoints on typical internet voip services.

Thanks Regs.  Have you got any experience with FX Networks?  We've got a fibre connection with them, so they're kind of the obvious choice.  Not necessarily the cheapest, but we've had basically no trouble since it was installed.

I have taken a look at hosted Lync options, but we've got a pretty good IT team and server equipment in-house, plus we're working on becoming a MS Silver partner, which would give us a couple Lync Enterprise servers for nothing :-]

The benefit I see in the snom phones is the physical buttons.  The support staff in particular transfer calls round to each other all the time, so it's really simple to look at your phone, see who's free and hit a button, rather than either scrolling through the contact list on the phone; or click on the current call window, transfer, another person, find the contact, then OK.  4 clicks vs 1 button press.

If the Cisco SPA500 phones could do Lync presence, I'd snap them up, because with the sidecar they have the right number of buttons to get all of our staff on there, plus a couple of buttons for personal speed dials.

We have a couple of staff members who don't like change.  I'm sure you all know how it is... Going from buttons to software could be a nightmare for everyone else who works in the same office.  You should hear them complain about the Office ribbon...

How easy is it to pick up someone else's call in Lync?  We do that all the time if someone has popped away from their desk.  Most of us plebs don't have voicemail.

And/or, do you know if you can have options in Lync's voicemail - e.g. "Press 1 to be transferred to reception, or hold to leave a message?"  It would be handy for DDI's.

byronpaul will be able to give a much better response as he converted our own internal phone system to snomONE, but to quickly address this point:

BobTBunny: If we do go for a separate phone system I’ve been looking at either 3CX or snom.  Does anyone know why it seems so common to run snom phones on 3CX rather than snom ONE?  Am I right in thinking the snom ONE phone system can basically only use snom phones

snomONE has only fairly recently become a snom product, previously it was known as pbxnsip.

The free version of snomONE allows a maximum of 10 snom phones or a maximum of 5 non-snom devices (you can do 5 non-snom + 5 snom). No such snom-only limitations exist however in the commercial versions. Here we have a mixture of snom and Yealink devices in use, and occasionally a Gigaset.
