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
configured to [1] Disconnect on AMD (see Configuring IP Profiles).
This feature is applicable only to the Gateway application (digital interfaces).
➢ 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).
2. From the 'AMD Mode' drop-down list, select Disconnect on AMD, and then click Apply.
