Chapter 3 Configuring the Cisco IPVC 3500 Series Gateway
Configuring Gateway Settings
•
Converts in-band DTMF signals from the ISDN-side endpoint to out-of-band H.245 signals if the
IP-side endpoint is located on an H.323 network.
• Passes incoming in-band DTMF signals to the IP-side endpoint unchanged.
This setting is selected by default. If unselected, the gateway passes in-band DTMF signals to the IP-side
endpoint unchanged. If you do select this setting, perform step 6.
Step 6
In the Apply to field, choose the type of calls to which ISDN-to-IP DTMF processing applies: Voice
calls or Voice and video calls . Voice calls is the default setting.
Note
Enabling DTMF detection for video calls reduces the number of supported calls at 128 Kbps
from 30 to 22.
