Note: Some endpoints such as Microsoft NetMeeting version 2.x do not support the RAS
protocol and cannot dynamically register with the Gatekeeper. In this case you have
to predefine the endpoint in the Gatekeeper Zone Definition table and define it as
“Online Always.”

To verify the destination gateway supports TCS4
You have to verify that the gateway receiving the call supports TCS4. The following steps
refer to a RADVision Gateway.
1. Run the OnLAN Configure 323 configuration software.
2. Open the Gateway’s WAN Port Settings screen and click WAN Call Parameters . The
WAN Call Parameters screen is displayed.
3. Select the TCS4 Enabled check box.
The IVR does not act in response to incoming calls
Not all endpoints support DTMF tones. If the dialing endpoint does not support DTMF
tones, the IVR forwards the call to the IVR operator if one is defined. Otherwise, the call is
forwarded to an enabled and defined Default Extension.
When the volume of the DTMF tones generated by the dialing endpoint is low, the IVR may
not recognize one or more of the tones. If the Gateway does not find an endpoint with a
phone number corresponding to the tones dialed, the IVR treats this string as an incorrect
number and disconnects the call.
Make sure that
