Yeah. It is worth mentioning that the SIPREC protocol used by DUB was created by the leaders of the telecom industry such as Cisco, NICE Systems, Genesys, Illinois Institute of Technology, Avaya, Siemens, Unify, among others. 

SIPREC was proposed as a draft in 2010 and approved as standard just in May 2016 (RFC 7866), after 18 modifications,long discussions and agreements from previous proponents. Many global players like Broadsoft, Oracle/Acme Packets, Metaswitch, AudioCodes, etc, realised about the benefit of this new recording protocol and adapted their UC systems or Session Border Controllers (SBC) to siprec or picked up one of the 18 drafts in the middle lol.

I think no new recording technology is coming in any time soon, since this standard has become widely accepted by the world's largest public telecom companies, due to powerful technical reasons.So, DUB is on the good track and 10 plus looks possible.
