Analog Wink-Start Trunks (Analog DID)
Analog wink-start trunks allow external callers to dial a user’s phone number directly,
without having to use an auto-attendant or operator. Analog wink-start trunks support
only inbound calls; they are not capable of handling outbound calls.
Analog wink-start trunks support:
Inbound calls (outbound calls are not supported)
ANI
DID
DNIS
Analog provisioning is provided by the wink-start protocol and Dual-Tone MultiFrequency (DTMF) signaling.
If ANI is being used, the star (*) key must be used to delimit the ANI digits from the DID/
DNIS digits—that is:
<DID>
<DNIS>
*<ANI>*<DID/DNIS>*
