An extension can use Pulse to Tone Conversion on trunk calls. Pulse to Tone Conversion lets a user change their extension dialing mode while placing a call. For systems in a Dial Pulse area, this permits users to access dial-up OCCs (Other Common Carriers - such as MCI) from their DP area. The user can, for example:
•Place a call to an OCC over a DP trunk.
•Depending on programming:
Manually implement Pulse to Tone Conversion
- OR -
Wait 10 seconds.
•Dial the OCC security code and desired number. The system dials the digits after the conversion as DTMF.
