Product Definition
What is a UIFN global customer hotline?
UIFN is a Universal International Freephone Number service based on the international +800 numbering range. It allows a business to use one number across multiple supported countries and regions.
Customers dial the number using the local international dialing method supported by their network. Incoming calls can then be delivered through SIP to a headquarters, cloud PBX, IVR, contact center, or remote support team.
Coverage, dialing access, and network availability vary by country, operator, and network type. UIFN should not be presented as an automatically global number.
One +800 number. One unified global customer service entry point.

or region must be reviewed and activated separately.
Actual dialing access depends on local operators, network types,
dialing rules, and current carrier support.
Mobile phones, public phones, hotel phones, and special networks
may be restricted or may involve additional charges.
Some markets require company documents, business proof, local
information, or end-user details.
