GXV-3000 IP Video Phone FAQ
1. What service providers or platform support the GXV-3000?
ITSPs with pure SIP proxy (e.g.: Iptel's SER); or ITSPs with hybrid SIP proxy (e.g.: Digium Asterisk™
R1.4, SBC or OBP) but supporting H.264 and H.263 when manipulating media.
2. What are the functions of the USB ports?
The 2 USB interfaces are USB 2.0 host ports. The
flash to store captured image, ring tones, phone address books (not implemented yet), etc.
When a USB flash drive is connected to the USB 2.0 port, an icon will display in the lower section of the
LCD.
3. Do I need a service provider? Can I make IP-to-IP call between video phones?
Yes, you need to have an Internet Telephony Service Provider (ITSP). You can also use "Direct IP Call"
to talk to each other in an ad hoc fashion without a SIP proxy. "Direct IP Call" can be made between
two phones if:
•
both phones have public IP addresses, or
•
both phones are in a same LAN/VPN using private or public IP addresses, or
•
both phones can be connected through a router using public or private IP addresses (with
necessary port forwarding or DMZ)
To make a direct IP call, press OK button to bring up MAIN MENU. Select "Direct IP Call". Press OK key
to bring up the input interface and then key in the 12-digit target IP address. Press OK key to initiate
call.
For example: If the target IP address is 192.168.1.60 and the port is 5062 (e.g. 192.168.1.60:5062),
input the following: 192*168*1*60#5062 -
to dial out.
Or, you can select:
Then use "#xxx#" to call where xxx is the last octet of the IP address if both phones are in the same
LAN.
For example: If the target IP address is 192.168.1.60 and use default port 5060, then you can just off
hook the phone and press "#60#" or "#60" followed by SEND key to make the quick IP call. This is very
useful in an enclosed LAN environment where you can assign static IP based on, for example, room
number in a building.
4. The bandwidth of my internet connection is very low. How do I set up the video phone in this
situation?
128kbps
You need at least
work with good picture quality.
128kbps
If using less than
(lowest) and Video Bit Rate to 64kbps or even 32kbps (lowest), to see if the video quality is
acceptable in your network environment. Otherwise, please upgrade your bandwidth as you don't have
enough physical data pipe to run the video data stream.
