Peer to Peer

An IP telephone can send and receive RTP packets to/from another IP telephone without using the DSP

resources on the PZ-32IPLA, PZ-64IPLA or PZ-128IPLA Daughter Board. This operation only allows

intercom calls between the IP telephones.

If a DT700 IP multiline telephone, or trunk line is required, a DSP resource is needed and a PZ-32IPLA,

PZ-64IPLA or PZ-128IPLA must be installed on the CPU. If, while on a peer to peer call, a conference

call is initiated, the peer to peer connection is released and a new non peer to peer connection is created

using the PZ-32IPLA, PZ-64IPLA or PZ-128IPLA. If the third party drops out of the conversation, the call

reverts to a peer to peer call (silence may be heard while this conversion is made by the system).

Although the peer to peer feature is supported for IP Station-to-IP Station calls, the UNIVERGE SV8100

chassis must still have a registered PZ-32IPLA, PZ-64IPLA or PZ-128IPLA installed in the system.

With Barge-In, a short silence may be heard if the following occurs:

A peer to peer call receives a Barge-In without a Barge-In tone.

A peer to peer call receives a Barge-In with Monitor mode.

When the established Barge-In is disconnected.

Peer to peer is a programmable feature that may be enabled or disabled (Program 10-26-01).

System Tones and Ring Tones

IP telephones do not use Program 80-01: Service Tone Setup entries. The tones are generated locally

by the IP telephone. When a Door Box chime rings an IP telephone, the system activates the chimes

using a ring command. Because of this, if the volume is adjusted while the door chime is sounding, the

ringing volume of the IP telephone is also adjusted.

Music on Hold

Music on Hold is also provided by the IP telephone. The settings in Program 10-04: Music on Hold Setup

are ignored except to determine whether or not music should be provided. If Program 10-04-02 is set to

0, music on hold is not heard. If Program 10-04-02 is set to 1 or 2, music is provided by the IP telephone.
