AudioCodes Mediant 500L - FXO Operations for Tel-To-IP Calls; Automatic Dialing

User's Manual 628 Document #: LTRT-10532
Mediant 500L Gateway & E-SBC
The "start dial" signal is a wink from the PBX to the FXO device. The FXO then sends the
last four to five DTMF digits of the called number. The PBX uses these digits to complete
the routing directly to an internal station (telephone or equivalent).
Note:
• DID Wink can be used for connection to EIA/TIA-464B DID Loop Start lines.
• DID service for FXS interfaces is also supported.
