IP Gateway: Disadvantages
Solves single issue: IP connectivity (temporary)
Closed system; not flexible/not upgradable
Limited solution; it becomes redundant when an
IP-PBX is implemented
Different products for HQ and remote offices;
could lead to compatibility issues
Will never replace the PBX, so maintenance fees
and utilities costs are ongoing
…and worst of all…

Transitional Approach Highlights
Get all the benefits of the IP Gateway, plus…
Dozens of IP-PBX features, including:
IVR system
Voice mail, Voice mail to e-mail
Conference bridge
IP trunks (low cost telephony providers)
Additional extensions (analog, IP)
Fax-to-mail
…and best of all…

Transitional Approach Overview
Three Phases:
A. Add IP Phones + Remote IP-PBX
(3 legged: PBX, PSTN, IP/LAN/WAN)
B. Add more ports and trunks
C. Disconnect the legacy PBX
www.xorcom.com
Transitional Approach: Phase I
Add IP-PBX – risk-free
Integrates into existing system via PRI
3-legged solution: PBX, PSTN, IP/LAN/WAN
Operates as a ‘smart gateway’
Provides connection to:
• remote offices
• tele-workers
• telephony providers (SIP trunk)
• all IP-PBX features

Comparison of Approaches
IP Gateway Approach
Solves single issue:
IP connectivity (temporary)
Closed system = not
flexible/not upgradable
Limited solution = becomes
redundant when IP-PBX is
implemented
Different products for HQ and
remote offices
Will never replace the PBX,
maintenance fees and utilities
costs are ongoing
Transitional Approach
Solves multiple issues: full IP-
PBX functionality
Open system = continually
being enhanced
Evolving solution = provides
leading-edge telephony when
you decide
Same products for HQ and
remote offices
Replaces the PBX at any time,
eliminating maintenance fees
and utilities costs
