Peer-To-Peer Connection - Panasonic KX-TDE100 Features Manual

1.31.3 Peer-to-Peer Connection

1.31.3 Peer-to-Peer Connection
Description
This PBX automatically establishes peer-to-peer communication between peer-to-peer compatible IP
extensions (i.e., IP-PTs and SIP extensions). Non-peer-to-peer IP extension calls are routed through the
DSP card. However, with peer-to-peer calls, the call is routed directly from one IP extension to another without
going through a DSP card. In other words, peer-to-peer calls can be made without using the PBX's resources.
Conditions
•
Peer-to-peer calls can only be made between extensions connected to the PBX through the IPCMPR/
IPCEMPR card.
•
The following combinations of IP telephones are peer-to-peer compatible:
KX-NT265
(version 2.00 or later)*
KX-NT300 Series
SIP Extension
ü: Available
*: For details about checking the version of the KX-NT265, refer to the Installation Manual.
•
The types of CODEC available for peer-to-peer calls depend on the IP telephones being used, as follows:
KX-NT265
(version 2.00 or later)
KX-NT300 Series
SIP Extension
The speech quality of the CODECs varies as follows: (High) G.722, G.711, G.729A (Low).
When the preferred CODEC of each party differs, the call will be established using the lower CODEC. For
example, if the caller prefers G.711 while the called party prefers G.729A, the call will be established using
G.729A.
•
G.722 is only available for the KX-NT300 series IP-PTs and some SIP extensions that support this CODEC
during peer-to-peer communication.
•
Through system programming, it is possible to assign a specific type of CODEC to be used for each
extension.
•
For SIP extensions, the priority of the CODEC that will be used can be specified on a SIP extension basis.
•
For non-peer-to-peer calls via the DSP card, calls cannot be made or received when all of the card's
resources are being used.
