SHARED-TENANT SERVICES ARRANGEMENT PROVIDING NUMBERING-PLAN INDEPENDENCE AND CROSS-PLAN ACCESS TO TENANT GROUPS
摘要
In a shared-tenant services arrangement, numbering-plan independence and cross-plan access is provided to tenant groups by a call-processing arrangement that stores separate definitions of both syntax and grammar of each group's own extension numbering plan. In response to receipt from a member of an individual tenant group of an extension number unaccompanied by a network dial-access code (DAC), the received extension number is analyzed using the syntax and grammar definitions of the extension numbering plan of the individual group. But in response to receipt from the member of the extension number accompanied by a DAC, the DAC is analyzed using the syntax and grammar definition of the extension numbering plan of the individual group to determine an extension numbering plan that corresponds to the received DAC, and the received extension number is then analyzed using the syntax and grammar definitions of whichever extension numbering plan corresponds to the received DAC.
