Moving towards Cloud PBX
The rapid rise of Microsoft’s Skype for Business is a strong incentive for enterprises to consider deploying the popular Unified Communications suite. The Company’s most recent announcements regarding their on-line version and the replacement of on-premises based PBX with Cloud PBX are also compelling in a period in which the trend to the Cloud is almost universal. However, despite the technical and business advantages of Skype for Business UC, there are many reasons why organizations might want to hold on to a legacy voice system on a temporary or permanent basis. Reasons vary and can range from the need to maintain specialized functionality such as contact centers or alarm systems to investment protection for legacy equipment, to the current functionality gap between the on-premises and cloud-based offerings and even objective availability and regulatory requirements which may mean that Skype for Business Online may not be available at various locations around the world for the foreseeable future.
Planning the Migration to the Cloud
As such, in almost any scenario in the coming years, most enterprises will likely be implementing a migration strategy from a legacy TDM or IP-based PBX system to Microsoft UC, as for all but the smallest of organizations, a full switchover is simply not practical. A smart approach would be to gradually migrate workers who can benefit from the cloud today while keeping other workers who need the full feature set or have other reasons requiring on-premises PSTN connectivity as described above, on the local Skype for Business Server in the near term.
Perhaps the most important thing an enterprise should do in this regard is to develop a voice migration strategy. Such a strategy would compose of several stages including assessing corporate requirements (typically in the headquarters), building an infrastructure that meets those requirements, migrating relevant users to the cloud and finally, expanding that migration by assessing the needs of branch offices, building a corresponding infrastructure and migrating branch users to the cloud as required. By deploying a hybrid system such as AudioCodes’ CloudBond 365, enterprises can benefit from the essential functionality required to ensure a smooth migration to Skype for Business enterprise voice. This can include:
- Hybrid and pure SBCs which ensure full interoperability between Skype for Business and legacy systems
- Active Directory integration which enables administrators to control how calls are routed during the migration
- SBC provided secured SIP trunking connectivity for after the migration is completed
Migrating Smart with a Hybrid System
A deployment of Skype for Business which mixes on-line and on-premises functionality will lay the foundation for a smooth transition to the full cloud solution down the line. The best way to protect the enterprise’s current investments, ensure a full enterprise voice feature set, guarantee that all company branches around the world are serviced and comply with regulations, is with a hybrid solution which offers the best of both worlds and allows the benefits of Unified Communications today with a secure and smooth migration to voice in the cloud when the time is right in the future.
