A. General Questions

The value of “Minimum =” means minimum delay. The value of “Maximum =” means maximum delay. “Average =” means average delay. “ms” is time value(1/1000 sec). The minimum and maximum time delay of package to the destination is 151ms and 300ms respectively. The average delay is 240ms.

(ii) Jitter

Jitter can be identified by the comparison between Maximum/Minimum Delay and Average Delay. The difference between them is the jitter level.

(iii) Package Loss Percentage

In “Lost = a (b% loss)”, “a” means the quantity of package loss, “b” means the percentage of package loss.

A. For the following:

(i) Public IP dials to regular phone

(ii) Caller and receiver both are in public IP

(iii) Caller and receiver both are in private IP

You can check the network quality by ping XXXXXXX(IP address of the opposite) to get package loss percentage.

B. For other circumstances

You can check the network quality by ping XXXXXXX(Server DNS) to get package loss percentage.

2. I am using Switch or HUB, which kind of Ethernet cable I need to connect to my phone?

Select Straight-through Ethernet cable for Switch and HUB; Try both Straight-through and Cross-Over Ethernet cable for other Ethernet devices. (Such as XDSL adapter, Cable Modem or PC, etc.)

3. I use the LAN port of my phone to connect to the Internet and use the PC port of my phone to connect to the PC, but the PC cannot get online.

Reason: The phone and the PC only have one IP, so they cannot use net at the same time. The ports of RJ45 phone are similar to a 2Port HUB. It does not have the router function of NAT, so it cannot serve as a router.

You just need to add Router or proxy server with NAT function in the front of your phone. Using the LAN port of your phone to connect to the Router or proxy server and using PC port of your phone to connect to the PC. In this situation, your phone and your IP can acquire different IP, thus get online at the same time.

If the problem is not solved, contact your agent to check any problem of the network connecting ports.

4. Selection of GK Zone

In some cases, you don’t need to input ‘service address’ manually but only to select a GK zone.

Zone 0 for users all over the world except china

Zone 1 for users who inside CHINA

If the problem is not solved, contact your agent to check any problem of the network connecting ports.

2. I connect my phone to the Ethernet port of Router, but my phone cannot acquire IP.

Reason 1: Incorrect ports connection

Check whether your phone connected to the Uplink port of Router. Do not connect to the Uplink port.

Reason 2: Some Router would lock on the MAC addresses of network devices.

3. Call quality

(i) Voice Delay

It always caused by the network delay. You can test the delay by using a PC which connects to Internet and in the same subnet of your RJ45 phone. Refer to General Question 1 for detailed testing instruction.

(ii) Voice jitter

It always caused by the network jitter. You can test the jitter by using a PC which connects to Internet and in the same subnet of your RJ45 phone. Refer to General Question 1 for detailed testing instruction.

(iii) Voice loss

It always caused by the package loss of the network. You can test the package loss percentage by using a PC which connects to Internet and in the same subnet of your RJ45 phone. Refer to General Question 1 for detailed testing instruction.

To protect the voice quality, require the network:

l Delay: less than 400ms

l Jitter: less than 100ms

l Package loss percentage: less than 10%

l Bandwidth: more than 30Kbps
