9. Auto Reboot

Reboot Time
This option allows the device to reboot itself at the time defined by Reboot
Time.
This parameter specifies the time to reboot the device. Two formats are supported:
1. HH:MM - When this is specified with a valid 24-hr time format (00:00 to 23:59), the
goip is rebooted at this specified time. Invalid time specified has no effect.
2.
M - This specifies the reboot duration in minutes. The valid range for this is from 0 to
x.
Changes saved are only effective after the device is rebooted.
Disabled
10. IVR The device is equipped with a simple voice prompt. When this option is
enabled and a call is answered, the device plays a voice prompt instead of a dial
tone to the caller.
Enabled
11. Remote SIM

Server

ID

Password

Net Protocol
Only the GoIPs with the serial number xxxx support the Remote SIM feature.
Enabling this feature allows the SIM Cards to be installed in a SIM Bank rather
than in the on-board SIM slots. GoIP can either register to a SIM Bank or a SIM
Server. Please refer to the SIM Bank User Manual for more information.
This specifies the IP address of the SIM Bank or the SIM Server.
This specifies the name to be appeared in the SIM Bank or the SIM Server.
This specifies the login password to the SIM Bank or the SIM Server.
Specify the network protocol (UDP or TCP) is used for Remote SIM communications.
Disabled
12. SMPP SMSC This parameter enables the support of SMPP protocol. Please note that GoIP
is acting as a SMSC (Short Message Service Center). Fill in the SMPP ID,
Password, and port number for SMPP data communications.
13. DTMF Tone
Min Gap (200 -
400)
This parameter specifies the maximum dropout time for a DTMF tone.
When making a call from SIP to GSM or
from GSM to SIP by using the second dial
method, the device needs to detect the
dialing digits from the DTMF tones
received via the voice data stream.
Depending on the network conditions, short dropouts may occur due to packet
jitter / loss. Therefore, DTMF digit may be detected more than once if these
dropouts are not taken into account. Consequently, the call is dialed to an
incorrect number. To avoid this problem, a dropout window is used to avoid
false detection when dropouts occur. During this window, the same DTMF
digit is not recognized more than once.
The range of the dropout window is specified in terms of packet timestamp
value. The smaller the value is, the smaller the dropout window is. This
increase the chance of detecting the same digit twice or more. However, if the
value is set too large, there is a possibility that the next digit is missed.

3.3.2Network
Proper network environment is the key to insure the voice call performance of the device. In general,
Intranet offers a more stable network environment than Internet and it is the preferred network to be used.
If Internet is going to be used, please make sure that the network can offer low packet loss, small packet jitter
and low packet delay.
Each voice channel requires less than 90 kbps when A-law or

-law voice codec is
used. GoIP-8 will require 8 times this bandwidth. Therefore, it is very important to make that both
upstream and downstream have enough bandwidth (+ 30% headroom) in order to accommodate the data
