Description
SIP (Session Initiation Protocol) is used for Voice over Internet Protocol. It is defined by the IETF
(Internet Engineering Task Force) RFC3261. Other RFC designations, such as RFC3842, refer to a
later implementation of SIP and may be supported by the UNIVERGE SV8100. Commonly called SIP
Station, this feature is used for IP Stations using SIP.
SIP analyzes requests from clients and retrieves responses from servers, then sets call parameters at
either end of the communication, handles call transfer, and terminates. Typically, such features,
including but not limited to Voice over IP services, are available from an SIP service provider.
Each PZ-32IPLA, PZ-64IPLA, or PZ-128IPLA application can support up to 16 TDM Talk paths. This
total may be shared among SIP Stations or SIP Trunks. Registered SIP Stations and/or SIP Trunks
require a one-to-one relation with the PZ-( )IPLA DSP Resource. This is a required component of SIP
implementation in the SV8100.
The UNIVERGE SV8100 CD-CP00-US contains a regular TCP/RTP/IP stack that can handle real-time
media, support industry standard SIP (RFC 3261) communication on the WAN side, and interface with
the PZ-( )IPLA.
SIP IP Stations use the PZ-( )IPLA. The IPLA controls and interprets RTP messaging from the SIP IP
Phone to the UNIVERGE SV8100 CD-CP00-US.
The IPLA supports only those codecs that are considered to provide toll-quality equivalent speech path.
The following voice compression methods are supported for the IP Station SIP feature:
G.711  -Law – Highest Bandwidth

G.722 – Wideband

G.729 – Mid-Range Bandwidth
