5.5 VoIP service configuration
The VoIP framework consisting of signaling protocols like SIP does not specify any
standard way or mechanism of implementing a configuration interface. As
implemented in the system, there are four possible sources of configuration
information for SIP. See Table 5-4 for the sources of SIP configuration data.

Source Description
OMCI OMCI communication is used to conduct service and protocol provisioning. OMCI data
is used to configure the overall VOIP service and individual POTS lines from the OLT.
A limited set of provisioning options for SIP are also provided using OMCI. When using
OMCIv2, additional TL1 provisioning options can be sued. OMCI data is established
using TL1 or SNMP commands at the OLT.
OMCIv1 allows configuration of proprietary options using TL1. OMCIv2 allows
configuration of standards-based VoIP service, POTS line, and SIP commands. Those
SIP commands that cannot be configured using OMCIv2 are listed in Tables 5-8 to
5-12.
OMCIv2 configuration support is available for Release 04.02.02 and later.
DHCP IP addresses that are used for the voice service can be manually selected and
entered or automatically obtained. As an option to manual IP address provisioning,
a DHCP server can be used to automatically obtain IP addresses.
