Recommendation ITU-T H.460.7 specifies the usage of Digit Maps within ITU-T H.323 systems. Digit Maps can improve the post dial delay experienced by the user and can reduce the amount of provisioning that would otherwise have to occur in order to reduce such delays.

This revision introduces a number of corrections and clarifications by incorporating technical and editorial corrections from the ITU-T H.323-series Implementers Guide (03/2011).
