Here is a 1-paragraph summary of the text:
Twilio has announced an enhancement to its Calls Per Second (CPS) feature for SIP Trunking termination, called Master CPS, which allows users to save money and gain more control over capacity planning. With Master CPS, users can provision their master account with the required CPS for each region and pay per region, rather than paying per trunk or channel as in traditional CPS. This new feature is available in beta and is ideal for businesses with multiple trunks across sub-accounts that need increased CPS but are unsure of their exact requirements. Master CPS provides a pooled resource used by any trunk in the given account or corresponding sub-accounts, allowing users to over-provision on the trunk level while only paying for the maximum required at the master account level.
