Hi there,

I'm experiencing trouble with web calls from an office location dropping out every 15 or so minutes. From home I have no trouble and can sustain a web call for 30mins or more without dropouts, but at the office it connects, works for about 15mins then drops and I have to re-establish the call. The internet connection itself is fine at the time of the dropout, i.e. an IE download in the background continues uninterrupted, and I can re-establish the call almost immediately. Any suggestions as to what this might be? Are there settings that might need to be changed on the office firewall?

Thanks in advance,

Lionel

Hi Lionel,

.....Sorry to hear about the connection problems. Please do this qualitative bandwidth test to see what is going on with your connection:

Hi Dave,

Thanks for your reply. It's a pretty basic connection here so the results aren't surprising:

• Jitter is red at 46.1 ms
• Packet loss is yellow at 4.1%, and
• Upload speed is yellow at 57.0 kbps.

Here are the results:

• Download bandwidth: 415 kbps
• Upload bandwidth: 57.0 kbps
• Quality of service: 93%
• Jitter: 46.1 ms, and
• Packet loss: 4.1%

Appreciate your suggestions.

Hi Lionel,

………..Thanks for testing.

There are two problems.

1.)    Your upload bandwidth is far below the minimum required 96 kbps. At 57 kbps, I am surprised that you were able to connect at all. I am also surprised that this is a business connection since the upload is in the range of Dialup (56 kbps). ooVoo requires broadband.

2.)    Jitter – you got a “Red”  reading for Jitter. So it is understandable that your connection drops.

Jitter is a variation or dislocation in the pulses of a digital transmission; it may be thought of, in a way, as irregular pulses. Jitter can manifest through variations in amplitude, signal strength, and other elements of such waves. The usual causes include connection timeouts, connection time lags, data traffic congestion, and interference. Simply put, this jitter is an undesirable output of system flaws and interruptions.

To fix the jitter problem, contact your Internet Service Provider (ISP) and tell them you need this fixed.
