• The VoIPDB uses two addresses, one address is for signaling and the other address for voice
traffic.
• An on-board RJ-45 connector provides a WAN/LAN connection. Voice and signaling data to/from
the IP Stations are converted into IP Frames and transmitted through the Data Communication IP
Network.
• The VoIPDB supports a maximum of 32 VoIPDB connections.
• Duplex mode (Auto or Full) and speed (10 or 100 mbps) are configured via SL1100 unit
programming.
In voice communication, particularly Internet telephony, the
M
ean
O
pinion
S
core (MOS) provides a
numerical measure of the quality of human speech at the circuit destination. The scheme uses
subjective tests (opinionated scores) that are mathematically averaged to obtain a quantitative
indicator of the system performance. The maximum MOS is 5.0.
• SL1100 supports a 100 rel option and Session Timer option.
• SL1100 supports Early Media.
• SL1100 SIP restricts an outgoing call under the following conditions:
- SIP configuration failed
- SIP registration failed
- Lack of VoIPDB resource
- Lack of a VoIPDB bandwidth
• Both port numbers can be configured by system data.
• ToS Support.
Conditions
• Documentation for Polycom devices are available at

• SIP Stations which support RFC 3842 (Message Waiting) receive Message Waiting Lamp
indications.
• SIP Station - VoIPDB does not support NAT traversal.
• SIP Station - VoIPDB does not support a Blind Transfer feature.
• Supports video codecs H.264, H.263, and H.261.
• Video is supported when P2P for standard SIP is turned on. (PRG 10-26-03 SIP Peer-to-Peer Mode
ON)
• Auto start video when call is answered is not supported.
• SIP Station and SIP Trunk require a license key for activation. Once activated, the SIP Client
license may be shared between SIP Station and SIP Trunks.
• SIP protocol (RFC3261) is used.
• SIP Station uses the VoIPDB as a media gateway.
• Default UDP listen port for a SIP station is 5070. Both port numbers can be configured by system
data.
• SL1100 Station registration policy supports an authentication feature. Enabling this policy prevents
the registered telephone from unexpected override.
• SL1100 supports HOLD and TRF feature on the basis of IETF draft.

• When all VoIPDB DSP resources are busy, the SIP Terminal cannot preempt active calls to make a
911 call.
• The SL1100 CPU is the registration server for the SIP stations. The configurable IP Address is
located in PRG 10-12-09 (SL1100 Network Setup - IP Address).
