Instruction
After a phone number is entered, dial # to call out immediately or, wait until the “Inter DTMF Timeout” expires (defined in “Advanced Options”, default=4 seconds).
If the phone number fits the setting of Digit Map, the gateway dials out the phone number through the assigned interface automatically.
The phone number should have at least 2 digits (not including * and #).
Dialed Number Processing Flow
To maintain maximum flexibility, the number dialed will be looked up from several tables defined in the gateway. Once no match can be found, it will look up again from the registered SIP Proxy Server. The look up flow is shown below:
Speed Dial
Table

Local Phone
