No Dtmf Tone At Remote Site; Noticeable Echo; Cannot Receive Any Incoming Calls; Warnings - NetComm V100LS Quick Start Manual

No DTMF tone at remote site

If the remote site cannot hear the DTMF tone that generated locally, please try different DTMF
relay mode (in audio or RFC 2833).

Noticeable echo

If you experience noticeable voice echo, you might increase "Echo Cancellation Tail Length"
to a larger value in order to remove the echo. The default setting "48 ms" is suitable for most
cases.

Cannot receive any incoming calls

If you cannot receive any incoming calls, please make sure you untick the "Enable
CallForwarding Unconditionally". This function blocks every incoming call and forward all
incoming calls to the phone number you specify in configuration.

Warnings

The "ATA Timeouts" values are optimized value for most cases, please do not change them.
Improper values will influence successful rate of VoIP calls
Please do not change the default settings in "advance settings" section, such as "configure
VAD and CNG", "Hook Flash Time" and "ATA Ring Tone Configuration", unless you know
what you are doing. Any mis-configuration in these areas might cause the ATA malfunction.
And the problem is hard to be diagnosed by end user.
