Solution
Feature
IPO SCN Server Edition Multi-Site Server Edition Comments
Topology
Freeform
Star, mesh, chain
SCN trunks anywhere.
Single or double star.
No additional SCN trunks
Restricted topology allows many
optimizations.
Other H.323 trunk types still allowed
Administration Limited centralized (SCN Manager)
Fully centralized (Server Edition
Manager)
Consolidated mode for full
centralization. Non-consolidated
mode for freeform per device
conguration
Licensing Distributed Central pool
All common licenses centralized
Some still distributed
All administered centrally
SSL VPN Separate independent access
Integrated access via Server Edition
(SE) Manager
Allows remote solution management
behind Services VPN Gateway
O/G Call Routing Complex, no default assistance Simplied
SE Manager and default routes allow
simpler O/G call routing
I/C Call Routing Complex, no default assistance Simplied
Common ICRs allow simpler I/C call
routing and resilience
Time Freeform/complex
Simplied by default, can still be
freeform
Primary Server acts as solution time
server by default
System directory Freeform/complex
Simplied by default, can still be
freeform
Primary Server acts as solution
directory server by default
Fax transport
IP Ofce T.38 fax transport across
SCN
G.711 fax transport across SCN
No need to congure codec sets to
enforce; G.711 fax transport used
automatically
SIP Trunk Direct Media to remote
device across SCN
None
Direct media supported to remote
H.323 and IP DECT endpoints
Includes SIP Info and RFC 2833
support
Phone Resilience Admin Freeform/complex Simplied
SE Manager admin allows only
Primary and/or Secondary to act as
phone backup server
Hunt Groups Freeform Hunt groups only on primary
Performance optimized for VMPro
location (also on Primary)
Automatic resilience when secondary
present
Overcomes SoftConsole limitations
SoftConsole Up to 4 per IP Ofce Up to 10 on Primary
Overcomes SoftConsole IP
connectivity and SCN limitations
IP Phones with no default user Not resilient Resilient Allows hot desk phones to be resilient
Add/remove node Manual Integrated via SE Manager
Auto population of Multi-Site links
and common conguration
Ofine device Cannot be managed Managed via SE Manager Includes online/ofine synchronization
Device Status/connectivity Not checked
Access and interconnects checked by
SE Manager
Immediate indication if device ofine
or incorrectly networked
SCN trunk channels Limited by licenses Unlimited No multi-networking license required
IP Ofce Initial conguration Manual
Automated with Initial Conguration
Utility (ICU)
Remote install technician without IP
Ofce knowledge
Upgrades Individual Centralized
Upgrades to all remote nodes can be
performed from Primary Location
Backup/restore
Individual per IP Ofce and per
application
Centralized Security settings not backed up
