As compared to the legacy-based plain old telephone service (POTs), VoIP provides feature rich capabilities along with better quality of services, feature management and advanced integration with other applications. With the sun setting for POTs services, all forms of telephony communication will be migrating to VoIP systems. The FCC document from 2015, however, reported that there would still be around 65 million switched access lines or POTs services in the United States. Businesses are concerned about performance of VoIP, and have resulted in slow migrations from POTs to VoIP but with mainstream implementation of SDWAN solutions, the issues with VoIP are definitely getting mitigated. Inclusion of millennials in the work force and the current trend towards digital transformation have pushed the innovation to integrate VoIP with collaborate applications as well as backend customer relationship management tools.Legacy Systems and VoIPThe legacy POTs system had copper wires terminated all the way from the service provider's network into the customers premise. On the other hand, VoIP services uses the broadband circuits provided at the customer's premise for other data communications. Typically VoIP technology involved phones converting analog signals into digital packets which are routed from the customer's local area network (LAN) via the Wide area network (WAN) through the internet into the service provider's network. There have been challenges with voice packets competing with other data traffic through the network. This results in impacting the performance of the services leading to degraded service. VoIP providers have managed this issue by prioritizing the Voice packets, tagging them for the highest quality of service and also by ensuring the customer's WAN FVILAS UCHIL, DIRECTOR OF NETWORK ENGINEERING, BULLSEYE TELECOMVilas UchilVOIP, SDWAN AND MILLENNIALSIN MY VIEW
