2.5.5 QoS settings
AT-530 IP phone implement QoS based on 802.1p, The QoS is used to mark the network
communication priority in the data link/MAC sub-layer. AT-530 will sorted the packets
using the QoS and sends it to the destination.
VLAN Enable: If enable the VLAN service, the second layer will realize separate voice,
signal and data transmission. To realize separate voice and data transmission by dispose
for IP precedence of ToS area of voice transmission. To reach upper layer switch or router
have priority to transfer voice transmission. (The prerequisite is the upper layer switch or
routers have to identify ToS area.)
VLAN ID: Dispose VLAN ID is add a Tag header after realize enable the VLAN function.
The realized voice packets transfer at the same VLAN. The prerequisite is it must the
same as VLAN of upper switch. The value range are 1~4094.
DiffServ Enable: If enable the VLAN service, it indicates use DSCP mode to realize three
layers QoS. This moment, the DSCP of SIP signals which between IP Phone and MGC. It
will use Class Selector 5 (The value is 0xA0). And the DSCP of mediums information (In
RTP packets) would be used the values of DiffServ Value field.
DiffServ Value:The value range：
0x28,0x30,0x38,0x48,0x50,0x58,0x68,0x70,0x78,0x88,0x90,0x98,0xb8.default is
0xb8 ,oxb8 stands for best fast transmission; 28-30 is guarantee for the transmission
priority for the 1st rank , 48-58 is guarantee for the transmission priority for the 2nd rank,
68-78 is guarantee for the transmission priority for the 3rd rank, 88-98 is guarantee for the
transmission priority for the 4th rank.

2.5.7 Digital Map
Digit map is a set of rules to determine when the user has finished dialing.
NG-188 support below digital map:
Digital Map is based on some rules to judge when user end their dialing and send the number to
the server. NG-188 support following digital map:
----End With “#”: Use # as the end of dialing.
----Fixed Length: When the length of the dialing match, the call will be sent.
----Timeout: Specify the timeout of the last dial digit. The call will be sent after timeout
----Prefix: User define digital map:
[ ] represents the range of digit, can be a range such as [1-4], or use comma such as [1,3,5],
or use a list such as [234]
x represents any one digit between 0~9
Tn represents the last digit timeout. n represents the time from 0~9 second, it is necessary.
Tn must be the last two digit in the entry. If Tn is not included in the entry, we use T0 as default, it
means system will sent the number immediately if the number matches the entry.
Example:
[1-8]xxx All number from 1000 to 89999 will be sent immediately.
9xxxxxxx 8 digits numbers begin with 9 will be sent immediately.
911 Number 911 will be sent will be immediately
99xT4 3 digits numbers begin with 99 with be sent after four seconds.
