Peer-to-Peer Audio for IP and SIP Devices
Peer-to-Peer Audio for IP and SIP Devices
The P2P audio feature, available in software v8.1 and later, allows certain IP and SIP devices
to transmit and receive audio directly with each other rather than through the system cabinet.
The P2P feature reduces delay and packet loss for IP and SIP devices.
Devices that support P2P audio include:
•
AudioCodes MP-114 or Quintum AFT 400 SIP gateway
•
IP endpoints, except the IP SoftPhone
•
Multi-Protocol endpoints
•
SIP endpoints
To use P2P, the IPRC and the IP and/or SIP devices must be upgraded with v8.1 firmware. In
addition, the devices must be programmed as members of the same Network Group. Calls
between IP and SIP devices that are members of separate Network Groups are routed through
the cabinet and do not use P2P.
Version 8.1 and later software supports a Network Group Diagnostics feature that allows an
administrator to verify that the Network Groups are programmed properly. See
for
instructions on how to use the Network Group Diagnostics feature.
IP devices that use P2P audio do not use cabinet resources when they are connected in a P2P
call. Therefore, the following features will not work during a P2P call:
•
Agent Help
•
Record-A-Call
•
Station Monitor
Inter-Tel Protocol (ITP) and SIP Operating Modes
The Models 8600, 8620, 8622, 8662, and 8690 Multi-Protocol Endpoints have the ability to
operate in ITP (formerly known as Axxess IP) mode or Session Initiation Protocol (SIP) mode.
The Models 8664, 8665, and 8668 wireless IP endpoints operate in ITP mode only. The Model
8601 endpoint operates in SIP mode only.
ITP mode supports nearly all of the system features except for the limitations listed on
. SIP mode offers basic endpoint features and the flexibility of shared extensions,
which means you can use one extension with up to five different devices on the telephone and
voice processing systems.
NOTE:
Endpoints may have certain hardware and software restrictions that prevent it from
fully supporting a feature. Consult the appropriate endpoint user guide to determine which fea-
tures are supported for your device.
NOTICE
Passing real-time streaming data, such as audio, through encrypted virtual private networks
(VPNs) may significantly impact the network performance, router and firewall functionality,
and audio quality.
