5-Site SCN Configuration 1

[dsm600rr]

Hello all,

Its been forever since I set up a SCN so I have some questions:

We will have the Main site and 4 remote sites.

Main site will have 4 SCN Lines Pointing to Remote Sites 1-4

Should each remote site's SCN Line all point directly back to Main?

Also trying to figure out licensing. Each site will only have 5 phones. I was thinking 2 SCN Voice Networking Channels for each remote site and 8 at main.

Thoughts?

I connect all of mine between each other so that the remote sites aren't piped through the main one for calls between each other.

I'd do 4 channels at each remote site, 8-12 at the main. (voicemail uses one of those channels for every action it does)

Having a SCN line between the main and remotes and a corresponding line on the remotes pointing back to main (star topology) is fine. If the data network isn't hub and spoke you can also build lines between the remote sites and other remote sites so they can still call each other if the main system is unreachable (mesh).

Licensing comes in 4 channel increments, so you'd probably be OK with 4 channels on each remote and 8 at the main site. If I remember correctly, a license is only used for an outgoing call, so a call from the remote to main consumes one channel license on the remote site but no licenses are consumed for an incoming call at the main site. That said, most all of my multi site work the past few years has been server edition, so someone may correct me if I'm wrong.

dsm600rr,
The way I do my configuration is have it so all sites could connect if need to.
So your third example is the best, but what if Remote site 1 needed to talk to Remote site 3.

Make 4 different SCN lines at each site,

Main Site
SCN Line 17 to remote 1
SCN Line 18 to remote 2
SCN Line 19 to remote 3
SCN Line 20 to remote 4

Remote 1
SCN Line 21 to main
SCN line 22 to remote 2
SCN line 23 to remote 3
SCN line 24 to remote 4

Remote 2
SCN Line 25 to main
SCN line 26 to remote 1
SCN line 27 to remote 3
SCN line 27 to remote 4

Continue similar examples for Remote's 3 & 4 (rather than me typing it all out).

I have this setup for a 6 site SCN, with just a 4 SCN Voice Networking Channels license at each location.
Never had the customer complain about not enough channels.
With you saying each site only having 5 phones, you should be ok.
My 6 site SCN has way more phones than that at all locations.

rcc1000: Appreciate it! Makes more sense now. Not sure why this is giving me a head ache haha

Yes, your last diagram looks correct (at least that's how I set mine up) & like biv343 said the license come in only 4 channel increments.

Thanks for the star.
