Is Your Network Ready for Hosted Voice? 10 Questions for Determining Your Cloud Readiness

  1. 1. Solutions you want. Support you need. Is Your Network Ready for Hosted PBX? 10 Questions for Determining Your Cloud Readiness Once you’ve decided to make the move to cloud communications, it’s critical to ensure the solution can interoper- ate with YOUR infrastructure. When selecting a hosted communications service provider, make sure they are willing and able to work with you to determine your state of cloud readiness and help you prepare your network for hosted communications. The checklist below is similar to the one that XO uses in the implementation of Hosted PBX solutions and will give you some examples of what a reputable provider may ask as they begin designing and provisioning your service. If a prospective service provider isn’t asking these types of questions about your business and your network’s readiness for hosted communications, ask yourself if the provider is truly qualified and prepared to host your voice communications. By using this list of questions, you will learn what’s essential for determining cloud readiness for a successful Hosted PBX implementation. Questions for Cloud Readiness Why this is important... 1. How do you plan to use the features of the Hosted PBX service and how are they essential to your business communications? The implementation phase is an ideal time to think about things like auto-attendants that automatically answer your calls, or hunt groups that quickly find an employee to handle customer calls. 2. Is Dynamic Host Configuration Protocol (DHCP), an auto- configuration protocol used on IP networks, configured on your LAN? If yes, does the provider require you to configure your server to operate with their equipment? Will the provider do this for you? 3. Is your network set-up to use Quality of Service (QoS) configuration? If not, the service provider should explain how it should be set-up. QoS is a key factor on the network. Without it, you will experience poor voice quality and dropped calls. Ask your provider to explain what end-to-end quality of service fea- tures they have implemented. 4. Do you understand the rules for the different types of traffic that must be allowed on your network/through your firewall? For example, these types of traffic are typical: • ICMP • UDP on ports 5060, 5061, and high UDP ports in the range 1024-65535 for call set-up and media • HTTP and HTTPS traffic for outbound web access • DNS lookups for SRV and A records used to locate and connect to the service Your calls need to be able to reach the cloud so that they can be processed. In addition, you will need to be able to reach the cloud from your web browser in order to configure services such as call forwarding. Your provider should be able to give you a definitive list of what needs to happen on your network and in your firewall to let this traffic pass. 5. Have you checked your switches and cabling to ensure they are optimized for VoIP? An outdated infrastructure can cause severe disruption to VoIP traffic. 6. Do you have any servers or other services hosted at the site that are accessed from outside? Is your provider aware of these? Understanding all traffic on your LAN/WAN is critical to assessing VoIP performance. 7. Are you using any existing VoIP-based endpoints? If yes, is your provider prepared to support these sites? If the provider is not willing to support your existing devices, you need to be prepared to rip and replace all of your phones.

Questions for Cloud Readiness Why this is important... 8. Do you require phones with Power-over-Ethernet (PoE) switches? If yes, ask if the service provider if the phones offered with their Hosted PBX service are equipped with POE switches. PoE switches allow you to plug in your phones wherever you can get a network connection rather than being limited to mains outlets. 9. Does your business require a solution for fax machines? If yes, ask if the service provider can support faxing with their Hosted PBX service. Many providers cannot handle fax, or other analog devices, at all. If this is the case, consider how you will handle both incoming and outgoing faxes outside of your Hosted PBX solution. 10. Are you prepared to work with your service provider as they perform a site survey and review the possible imple- mentation scenarios? The provider should be prepared to handle the scenario you require, such as separate network cabling for voice and data, or combining the two in a single wire.
