C. Timeout Setting

D. Signaling QoS

Quality of Service (QoS) is a network’s capacity to provide priority services,

including the special bandwidth, jitter control and delay (used for real-time and

interactive traffic), and improvement of the packet loss ratio. This parameter is

used to mark the specified QoS label for the call signaling packet to increase the

network service quality.

E. DTMF Signals

DTMF signals are used to transmit call signals to the call switching center over the

audio band. The DTMF means that two different frequencies of sounds are

combined into 16 types of dialing tones. The telecom office or 1860 service

hotline identifies these dialing tones through analyzing the DSP, and thus

determines the dialing number. There are two types of DTMF signals: in-band

DTMF and out-band DTMF.

1) In-band DTMF

The in-band DTMF transmit s dialing tones and call voices together, without any

processing. Therefore, the in-band DTMF transmits DTMF signals through a single

way.
