14.5.2 Enabling IP-to-Tel Call Disconnection upon Detection of
Answering Machine
The device can disconnect an IP-to-Tel call upon detection of an answering machine on
the Tel side. Once detected, the device disconnects the call after the receipt of an ISDN
Connect from the Tel side and then sends a SIP BYE message to the IP side to disconnect
the call. You can enable this feature for all calls (globally) using the AMDmode parameter
(see procedure below) or for specific calls using IP Profiles where the IP Profile parameter
'AMD Mode' (IpProfile_AmdMode) is set to [1] Disconnect on AMD (see ''Configuring IP
Profiles'' on page 438).
To enable disconnection of IP-to-Tel call upon detection of answering machine:
1. Open the Gateway Advanced Settings page (Setup menu > Signaling & Media tab >
Gateway folder > Gateway Advanced Settings).
