To provide good (or at least satisfactory) voice channel quality of your AMSD EasyTalk™ call to Moscow, the IP transfer timeout (from your ISP to our gateway) should not exceed 500 milliseconds. You can measure the actual timeout by running
tracert pstn-gate.amsd.com or ping pstn-gate.amsd.com
from the console (MS DOS window).
If the timeout value is lower then 250 ms, the quality of voice transmission will be excellent.
It the maximum timeout exceeds 500 ms, the voice stream may be transferred with serious delays. In this case we recommend you to change your ISP.
If the maximum timeout exceeds 800..900 ms, it will be virtually impossible to achieve a satisfactory voice connection between your computer and the phone in Moscow.
Therefore, before making test calls to Moscow (you can do it before ordering AMSD EasyTalk™; just request a "temporary" Serial Number for testing purposes), you should send us the ping logs generated by tracert or ping.
