6. Coding Principle
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:
