5 — VoIP overview
Feature Description
File download The configuration profile can be downloaded from a file server. The file server IP address is manually
provisioned or learned through the DHCP server. The name of the file is provisioned. The configuration
profile contains a set of characteristic data for the analog phone and the VoIP service. The data
includes:
•
impedance settings
•
gain settings
•
ringing cadences
•
tone frequencies and cadences
For the SIP modes, the profile data is expanded to include additional service configuration
parameters.
IP addressing Provisioning options are available to manually provision IP addresses through TL1, simple network
management protocol (SNMP), or learned through the DHCP or BRAS server.
MLT diagnostics The same mechanized loop test (MLT) diagnostics are available in both modes of operation.
Option 82 A provisionable string used by the DHCP relay is enabled on the service virtual local area network
identifier (1) (S-VLAN) with the configuration (CONF) option. The string allows a configurable identifier to be
associated with the VoIP service that is inserted by the DHCP relay agent at the P-OLT toward the
DHCP server.
Ping The ONTs support ping responses.

Note
(1) When another device is configured as the DHCP server and the system is configured as a DHCP relay agent, the Option 82
parameter should be enabled on both devices. This is to ensure that traffic passes correctly between the devices.
5.2 Voice gateway mode
In the G6 voice gateway mode, the H.248/Megaco protocol is used for call control
signaling between the voice gateway and the ONT. The system interfaces with the
voice gateway through a layer 2 Ethernet network. Using the H.248 protocol, the
voice gateway controls voice calls, including the bearer channel to carry voice data
between the voice gateway and ONT. The signaling and bearer end-points are
identical. This mode is not supported on package C, D, and I-240W-S ONTs.
