  1. Improving Customer Satisfaction Through Advances in Remote Management TechnologyGreg MichelProduct ManagerQuintum Technologies Inc.

  2. Introduction • Challenges of providing speedy and efficient customer support in enterprise networks • Ways of addressing these challenges • Drawbacks of current methods • Introducing a new paradigm • A new remote management technology • Benefits of this new approach

  3. Challenges • Most enterprises have strict security policies • Various NAT traversal solutions exist for VoIP access but not for device management • Direct access to gateways behind firewalls for management purposes is impossible • Greatly complicates the customer support process • Requires customer involvement in support issues • Adds delays, and extends customer downtime • May require expensive site visit or truck roll

  4. Enterprise Remote Configuration and Management Is Challenged By Firewalls Configuration and Network Management Tenor VoIP Gateway ? PSTN ? PBX IP IP Phones & Clients • Remote management is critical for “Customer Service.” • Service Providers, VARs, Integrators, Network Administrators. • Firewalls deny accessibility. • Establishing management sessions to all endpoints is not scalable.

  5. Possible Solutions • Install VoIP gateways outside firewalls • Usually unacceptable due to security issues • Install VoIP gateways in the DMZ • Better, but still not very appealing • Access gateways via a local PC running a secure client such as PC Anywhere • Requires involving customer personnel at the remote site • Use phone and e-mail communications with on-site customer personnel • Very slow and requires customer personnel involvement

  6. Firewall/NAT IP Network Router Install VoIP gateway in the public domain “Public” LAN “DMZ” LAN “DMZ” Port “Private” Port “Private” LAN • Install VoIP gateways outside firewalls • Usually unacceptable due to security issues • Open to denial of service attacks

  7. Firewall/NAT IP Network Router Install VoIP gateway in the DMZ “Public” LAN “DMZ” LAN “DMZ” Port “Private” Port “Private” LAN • Install VoIP gateways in the DMZ • Better, but still vulnerable • Open to denial of service attacks

  8. Firewall/NAT IP Network Router Install VoIP gateway on the private LAN “Public” LAN “DMZ” LAN “DMZ” Port “Private” Port “Private” LAN • Install VoIP gateways on the private network • Ideal solution from the enterprise point of view • Management access now becomes an issue

  9. IP Network PSTN Indirect access using phone and e-mail Customer Staff Customer Support Specialist Service Provider NOC • Indirect support • Extremely slow and inefficient • Requires skilled local staff involvement

  10. Firewall/NAT IP Network Router Use secure remote access software “Public” LAN “DMZ” LAN “DMZ” Port “Private” Port Secure Access Client Running on Local PC • Access VoIP gateways via a Secure Access Client • Adds cost at remote site, not scalable • Requires local support to enable secure access

  11. There’s got to be a better way ! • Need transparent, secure, direct access to CPE at the customer site, even if it is deployed behind corporate firewalls • Should provide access to install, configure, upgrade, and trouble shoot remote CPE with little or no local involvement • Should provide customer support personnel with a “just like being there” experience

  12. Introducing a New Paradigm –The Remote Management Session Server • Provides completely transparent, secure remote access to CPE behind corporate firewalls • Complete access to carry out all management and maintenance functions without local involvement • Standards based secure connection (SSH, SOCKS) • Encrypted connection supports HTTP, FTP, Telnet • “It’s just like being there” experience • Automatic notification of install via e-mail • Automatic download of logs via e-mail

  13. Enterprise Enabling Remote CPE Management –The Remote Management Session Server Configuration and Network Management Tenor VoIP Gateway PSTN PBX IP IP Phones & Clients Remote Management Session Server • RMSS sits on the public, or service provider, network and acts as a bridge between the Tenor and the management tools. • Network Administrators/Customer Support can manage access gateways anywhere.

  14. DHCP Pre-configuring the CPE equipment

  15. Connecting to the RMSS

  16. Select a unit from Registration List

  17. It’s just like being there -

  18. Benefits • Complete access for optimum customer support • Automates remote site installation process • No local customer involvement required • No skilled staff required at remote site • Much faster problem resolution • Minimizes customer downtime • Eliminates costly site visits or truck rolls • Greatly improves customer satisfaction • Leverages efficiency of customer support personnel
