Grandstream Networks, Inc. GXV3174 USER MANUAL Page 35 of 68 FIRMWARE VERSION 1.0.0.32 Updated : 11/2010 Tone disabled. Disable Direct IP Call The default setting is No. If set to Yes, Direct IP calling will be disabled. Offhook Auto Dial Configure a User ID/extension to dial automatically when the phone is taken offhook. By default, the phone will use the first account to dial out. Advanced Settings/Video Settings Enable Motion Detection The phone will exit idle/screensaver mode if motion is detected. The default setting is Yes. Video Frame rate The Default value is 15 frames/second. The video frame rate is adjustable based on network conditions. Increasing the frame rate will increase the amount of transferred data significantly therefore consuming more bandwidth. Lack of bandwidth will impair the video due to packet loss. Video Packet Size The Default value is 1400, range from 100 to 1400. It is recommended to use 600~800 if you have an Outbound Proxy or Media Gateway. Video Rate Control Frame, TMN8 or GOP. The Default setting is Frame. TMN8 is good for bandwidths larger than 384kbps Video Frame Skipping Skips bad video frames as they are received The Default setting is No. I-Frame Reference Only When enabled, all P frames will only have reference to previous I frames. This method may improve video quality when the network has heavy packet loss. It will have modest increase in bandwidth usage. The Default setting is No. Packetization-Mode The packetization mode (0 or 1) for the H.264 video packets. The default setting is 0. Redundant P-frame This setting allows the phone to send redundant P-frames of I frames. When an I frame is delayed or has packet loss, the redundant P-frames will be used instead. It may make video phone call less prone to errors and thus make the video stream more robust towards error propagation, but may increase bandwidth usage. The default setting is set to No. Adaptive MB Intra Refresh This parameter specifies whether Adaptive MB Intra Refresh is used or not. It may protect most important MBs (macro blocks) subjected to packet loss and to avoid error propagation. The intra-refresh rate is adapted according to the video packet loss rate. It may increase bandwidth usage. The default setting is set to No. Video Packet Loss Rate Specifies the video packet loss rate for the Adaptive MB Intra Refresh. Users can choose from: Less than 5%, Less than 10%, Less than 15%, Less than 20%, Less than 25%. The default setting is set to Less than 10%. Advanced Settings/Ring Tone Call Progress Tones: Dial Tone Ring Back Tone Using these settings, users can configure ring or tone frequencies based on parameters from the local telecom provider. By default, they are set to the North American standard. Frequencies should be configured with known values to avoid Grandstream Networks, Inc.

Syntax: f1=val,f2=val[,c=on1/off1[-on2/off2[-on3/off3]]]; (Frequencies are in Hz and cadence on and off are in 10ms) ON is the period of ringing (“On time” in ‘ms’) while OFF is the period of silence. In order to set a continuous ring, OFF should be zero. Otherwise it will ring ON ms and a pause of OFF ms and then repeat the pattern. Up to three cadences are supported. Default Ring Cadence This defines the ring cadence for the phone. The default setting is: c=2000/4000; MAINTENANCE PAGE DEFINITIONS Maintenance/Network Settings Address Type This selects the type of IP address assigned: DHCP, PPPoE or Static IP. PPPoE When PPPoE is selected, the user needs to enter the following: PPPoE Account ID, PPPoE Password, PPPoE Service Name. Static IP When Static IP is selected, the user needs to enter IP address, Subnet Mask, Default Gateway, DNS Server 1 and DNS Server 2. Alternate DNS Server This field sets the alternate DNS server for the user. Layer 3 Qos This field defines the layer 3 QoS parameter. It is the value used for IP Precedence, Diff-Serv or MPLS. The Default value is 0. Layer 2 QoS 802.1Q/VLAN Tag This field contains the value used for layer 2 VLAN tagging. The Default value is 0. Layer 2 QoS 802.1p Priority Value This assigns the priority value of the Layer2 QoS packets. The Default value is 0. 802.1x Mode This field sets 802.1x Mode. The default value is disabled. If EAD- MD5 is selected, users will be required to enter Identity and MD5 Password. Proxy This field sets HTTP Proxy, HTTPS Proxy, FTP Proxy or No Proxy. Using HTTP Proxy, other protocols can be applied by checking the box “Apply to Other Protocol”. Maintenance/Time Settings NTP Server This parameter defines the URL or IP address of the NTP (Network Time Protocol) server. The GXV3174 phone may obtain the date and time from the server. The default setting is ntp.ipvideotalk.com. DHCP Option 42 override NTP server Select Yes for the user to allow DHCP Option 2 to override the NTP server if there is one on the LAN.

Time Display Format This parameter sets time display format to 12 Hour or 24 Hour Grandstream Networks, Inc. GXV3174 USER MANUAL Page 37 of 68 FIRMWARE VERSION 1.0.0.32 Updated : 11/2010 Date Display Format This parameter sets date display format to YY-MM-DD or MM-DD-YY or DD-MM-YY. Self-Defined Time Zone This parameter allows the users to define their own time zone. Syntax: std offset dst [offset], start [/time], end [/time] Default is set to: MTZ+6MDT+5,M3.2.0,M11.1.0, MTZ+6MDT+5 This indicates a time zone with 6 hours offset with 1 hour ahead which is U.S central time. If it is positive (+) if the local time zone is west of the Prime Meridian (A.K.A: International or Greenwich Meridian) and negative (-) if it is east.
