Telephony – DID Numbers #
Once the SIP trunk has been configured, it is necessary to allocate numbers in Genesys to agents, handsets, voice menus or other functions.
In the Genesys Purecloud Admin page, under Telephony, select DID Numbers.
A range of numbers is defined using the DID Range tab, then Create Range, then enter the Start and End numbers of the range, and the Service Provider.
Numbers within a defined DID Range are assigned using the DID Assignments tab and can be assigned to a Person, Call Flow or Phone.
Once DID Ranges have been assigned, these numbers should be routed to the appropriate flows. Without any routing set-up, inbound calls will fail.
