Why international support is still a mess
Every customer-facing team wants local phone numbers in their key markets. Customers answer local numbers. They ignore international ones. Marketing knows this. Sales knows this. Support knows this.
But getting local numbers usually means signing up with a different provider per country, dealing with KYC paperwork for each, and stitching the numbers into your existing telephony stack. By the time the third number is provisioned, the project is dead.
You need international numbers without the international procurement.
