In the IP to ISDN Calls section of the Gateway-PRI, you can
select the Translate DTMF from IP out-of-band (H.245) to
ISDN in-band (G.711 only) check box.
In the IP to Serial Calls section of the Gateway-Serial, you can
select the Translate DTMF from IP out-of-band (H.245) to
Serial in-band (G.711 only) check box.
When selected, the LifeSize Gateway performs the following:
Converts H.245 out-of-band DTMF signals coming
from the H.323 IP-side endpoint to in-band signals on
the ISDN side.
Passes incoming in-band DTMF signals to the
ISDN-side endpoint unchanged.
This setting is selected by default. If deselected, the LifeSize
Gateway passes in-band DTMF signals to the ISDN-side
endpoint unchanged.
