Configuring Gateway Settings
5
In the ISDN to IP Calls section of the Gateway-PRI, you can
select the Duplicate DTMF signal from ISDN side as
out-of-band on IP side check box.
In the Serial to IP Calls section of the Gateway-Serial, you can
select the Duplicate DTMF signal from Serial side as
out-of-band on IP side check box.
When selected, the LifeSize Gateway performs the following:
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 deselected, the LifeSize
Gateway passes in-band DTMF signals to the IP-side endpoint
unchanged. If you do select this setting, perform
step 6 .

In the Apply to field of the Gateway-PRI, 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.
Remember
Enabling DTMF detection for Gateway-PRI video
calls reduces the number of supported calls at 128 Kbps from 30 to
22.
