The Average Call Duration (ACD) is calculated by taking the sum of
billable seconds (bill sec) of answered calls and dividing it by the number
of these answered calls.
PDD
Post Dial Delay (PDD) is experienced by the originating customer as the
time from the sending of the final dialed digit to the point at which they
hear ring tone or other in-band information. Where the originating
network is required to play an announcement before completing the call
then this definition of PDD excludes the duration of such
announcements.

4.5.2 ARP
The ARP function mainly used to query and add the map of IP and MAC. There are static or
dynamic ARP entries.
Like other routers, the gateway can automatically find the network device on the same
segment. But, sometimes you don't want to use this automatic mapping; you'd rather have
fixed (static) associations between an IP address and a MAC address. Gateway provides you
the ability to add static ARP entries to:
Protect your network against ARP spoofing
Prevent network confusion as a result of misconfigured network device

dialing. One stage dialing will obtain called number from INVITE message body,
either Request line or To <SIP:[email protected]> field. Then deliver called number
to GSM/CDMA directly.
But for two stage dialing, the SIP server must be dial the SIP channel account and
then to generate DTMF to mobile network.
Answer Delay
In most instances, Most of CDMA operators don't offer answer signal. The gateway
doesn’t response SIP 200 OK to SIP server in case of missing answer signal from
CDMA network. Answer delay is to fix this issue and generate SIP 200 OK to SIP
server after answer delay timeout. Default value is 5 seconds. Moreover, it is
available for CDMA gateway only.

Session Timer
SIP Session Timers which is an extension of SIP RFC 4028 that allows a periodic
refreshing of a SIP session using the RE-INVITE/UPDATE message. The refreshing
allows both the user agent and proxy to determine if the SIP session is still active. The
SIP Session Timer is a keep alive mechanism for SIP sessions that allow User Agents
(UA) or proxies to determine the status of a session and to release it if it is not active,
even if a BYE has not been received.

Session timer Interval
The initial INVITE request establishes the duration of the session and may include a
Session-Expires header and a Min-SE header. These headers indicate the session
timer value required by the user agent (UAC). A receiving user agent server (UAS) or
proxy can lower the session timer value, but not lower than the value of the Min-SE
header. If the session timer duration is lower than the configured minimum, the proxy
or UAS can also send out a 422 response message. If the UAS or proxy finds that the
session timer value is acceptable, it copies the Session-Expires header into the 2xx
class response.
A UAS or proxy can insert a Session-Expires header in the INVITE if the UAC did not
include one. Thus a UAC can receive a Session-Expires header in a response even if
none was present in the request. Its value range from 90-60000s.

6. The Way to Increase Antenna Isolation
Several methods are introduced in this document to decrease the interfering effect
among antennas with close mounting position.
6.1 Isolate by distance
figure-6.1 Theoretic distance value for GSM band
Keep distance between antennas as far as possible. In theory, the distance between
antennas should be more than half of the operating wavelength. For GSM band, the
recommended distance value is more than 20cm.in practical application, the
experiment value is no less than 15cm for better isolation.
6.2 Isolate by metal shielding baffles among antenna
Put a metal shielding baffle between antennas, which can help to prevent radiation
signal coupling from each other. If the metal baffle is big enough, the isolation
will be unlimited big in theory.
Figure 6.2 Isolation by metal shielding baffles

6.3 Isolate by antenna orthogonal polarization
Figure 6.3 Isolation by antenna orthogonal polarization
In theory, the isolation is unlimited big if the polarization is really orthogonal, like
vertical polarization VS horizontal antenna; RHCP (Right Hand Circular Polarization)
VS LHCP (Left Hand Circular Polarization).

DWG2000E/F/G GSM/CDMA VoIP Gateway User Manual
In real practical application, the antenna are all elliptic polarization, they have a
certain ratio. So putting the same type antennas in orthogonal position will be helpful
for isolation.
6.4 Isolate by antenna radiation pattern
Radiation pattern of low directivity antenna
radiation pattern of high directivity antenna
Recommended placement with nonmetal shelf

DWG2000E/F/G GSM/CDMA VoIP Gateway User Manual
Try to modify the antenna mounting position, avoid the major lobe of both antenna
overlap, which is also an effective way for high isolation among different antennas,
especially for high directivity antenna.
It might be difficult to find a perfect position to stagger the major lobe for low directivity
antennas, two factors cause this, one is the major lobe is very broad, the other is the
radiation pattern is affected by surroundings sensitively.
For common antenna we often use, most of them belong to low directivity type, we
can put the antennas in a nonmetal shelf, and place antennas in vertical form, not in
horizontal form, which can help to avoid antennas major lobe overlap and make the
isolation bigger in some degree.
7. Frequency Asked Questions
7.1 Device have been connected to network physically, but cannot access the
gateway
1) Make sure the network cable is ok , can through view the device network port indicator
light to determine the physical connection is working or not;
2) Make sure the connected network devices (router, switch or hub) support 10M/100M
adaptive, if not, connect the Equipment directly to PC, landing WEB and in the "local
connection" Configuration interface Select the correct Ethernet Work Mode;
3) Check the Network Configuration, if the Configuration is incorrect, please
re-Configuration. If you are using DHCP mode, check DHCP Server is working properly;
4) Check whether there is a LAN device conflict with the exists IP ADDRESS.
7.2 Equipment can not register
If the Run LED does not flash mean unregistered
1) Check the network connection is working (see above section), whether the Configuration
is correct;
2) Check whether the LAN firewall setting is inappropriate (such whether limit the network
communication); If it is, there are two ways to try to resolve;
3) Check whether the Local Network to the SIP PROXY platform network environment is
relatively poor or not, and if so, please check Local Network or contact the service provider;
4) if go through those steps, the device still be in trouble, please contact the equipment

provider;
7.3 When calling out, the callee’s phone shows wrong caller ID
1) Ask the callee checks whether the device is failure or device battery power is low
2) Make sure the callee has been subscribed called User ID display service
3) If only part of the caller User ID with this problem, please contact the telecom carrier.
7.4 Sudden interruption during a call
1) make sure whether is human error caused the problem
2) Check the balance.
3) Make sure whether the LAN equipment such as gateway or router fails, user can try to
restart the gateway or router
7.5 Voice single-pass, double-barrier or poor quality
1) Make sure the equipment is working properly with grounded power
2) Check the device network connection is in working status
3) Ask network administrators to open limitation with the equipment’s network
communications (it is a special equipment, not afraid of virus attacks); (2) try to enable the
equipment tunnel (through the WEB for Configuration, Also, please NOTE, open the
tunnel will impact voice quality, Please do not enable the tunnel as far as possible, refer
WEB Configuration Interface Description section)
4) Make sure the LAN equipment is working, user can try to restart the gateway or router to
solve the problem
5) Check whether there is more than one DINSTAR series products in LAN network: some
gateways or routers, processing network packet is vulnerable (for example, to multiple
network devices or the same protocol network communication, NAT allocated the same
conversion communications Channel). If there is such a case, suggest replacing a router or
specify each voice gateway with different LOCAL RTP PORT Channel (refer to the base
WEB Configuration interface section)
6) Check the equipment network environment for the softswitch platform, monitor the
network condiation, make sure the network is solid
