There is only so much SD-WAN vendors can do when it comes to VoIP and specifically WebRTC optimization. When a vendor claims for specific VoIP optimization that is based on quality of experience or similar considerations, I suggest to check the details of how this optimization is implemented and which applications it covers.
Delivery of WebRTC based communications services to the enterprise can be (and is today) done over best effort open internet but for higher adoption rates among enterprises it is required to enable the delivery of such services over managed networks.
The growing adoption of SD-WAN allows for agile and dynamic delivery of WebRTC services to enterprises
Having an SD-WAN solution integrated into VMware’s solution portfolio that takes VMware’s network virtualization from within the cloud to connecting enterprises with public and private clouds is important for VMware’s digital transformation and cloud strategy.

Although Cisco has a very strong position in the UC market, its strengths are mainly in UC of the past (on-premises deployments and telephony focused).
The acquisition of Broadsoft will help Cisco to better compete in the next generation cloud UC and team collaboration.
Overall a strong move of Cisco to help it compete with its rivals such as Microsoft and Slack.

There is no one good answer for the debate between on premise vs. managed and each of these options have sub-options to consider and decide on. The devil is in the details and in many cases a hybrid solution is required, using some functions (such as NAT traversal) from 3rd party hosted services while licensing (open source or commercial) other components of the solution.
