Local country standards
Beware of local technical and cultural differences
•  WAN termination or presentation – X21, G703 (75 or 125 ohm), T1, T3
•  Carrier demarcation – in data centre, office basement of separate area
•  Internet – IP addresses and sub nets, managed or wires only service
•  DDI ranges – number format variation, minimum PRI channels
•  Legal restrictions – VoIP, 3DES, in-country break-out
•  Cultural issues – national holidays and working hour restrictions
•  Service and billing restrictions – legal entity required in country
•  Serviced offices – ability to run dedicated client services
•  Language issues – ability to order what is required with confidence

Conclusion
Visibility is key
•  Define local, regional and global requirements
•  Is existing infrastructure fit for purpose
•  Identify manufacturer market penetration and support in each country
•  Understand carrier coverage and services available in each country
•  Understand local country service delivery standards
•  Blend manufacturer, carrier and functionality into suitable architecture
•  Highlight and address single points of failure
•  Test what has been ordered against what has been delivered
•  Ensure full visibility across all IP devices to allow proactive support
