5.5.2 VOIB (Voice over Internet protocol Board, 8 and 24channel)
The VOIB is available in two (2) models, the VOIP8 with 12 IP channels and the VOIB24 with 24 IP
channels. Other than the number of channels, there are no significant differences in the VOIB8 and
VOIB24. The VOIB provides the Ethernet interface for LG-Ericsson IP Phones, SIP phones and
trunks, IP Networking and applications. The VOIB is used to provide packet relay for remote devices
to communicate with the host and translate between the iPECS proprietary protocols and other
standard protocols (H323 rev.4, SIP RFC3261).
The VOIB connects to a standard IEEE 10/100 Base-T Ethernet switch port and supports auto
negotiation for speed (10MBps or 100Mbps) and full or half-duplex operation. The VOIB supports
various codecs (g.711, g.726, g.729, g.723.1), T.38 for IP FAX, and Echo Cancellation (g.168).
