Bandwidth Requirements and CODECs
To use the JTK system, there are a few requirements to be met:
- High speed, stable Internet connection. The minimum requirement
is 64 Kb/s in each direction or a total of 128kb/s. To verify connection reliability
you can use packet tracing software to reveal network problems. We recommend a product
called "Ping Plotter". You can download a free trial version at http://www.pingplotter.com.
- SIP IP phone, you can use a softphone if your PC has speakers
and microphone or a headset.
- A personal computer for account management.
- SIP IP phone must use G729 as the low bandwidth CODEC since
we do not support G723.
