IP ToS: Applied to RTP voice packets by default 
802.1p/Q: Automatically applied for RSGM and devices in Remote mode  
IPSec:  Two encryption algorithms (DES/3DES) & two hash algorithms (MD5/SHA-1) are 
supported 
STUN (Simple Traversal of UDP through NAT): Based on RFC3489, but modified to 
efficiently operate for Telenium

communications. 

PPPoE: Supported by phones and RSGM 
DHCP: Phones support DHCP client configuration in Remote mode 

RSGM supports DHCP client for WAN interface, and DHCP server (up to 50 
internal clients) on its LAN interface 

NAPT: Phones supported behind NAT/NAPT devices 

Router in RSGM provides NAT/NAPT support so that all clients can use private 
addressing 

HTTP: All devices except SHUB8 and POE8 have HTTP-based administration or upgrade 
capability 

Latency 

(delay) 

Less than 120 

milliseconds 

The duration it takes for a packet to move 

from one endpoint to another on the network. 

Jitter 

Less than 20 

milliseconds 

The variation in latency. When packets arrive 

at varying speeds, it can be disruptive to 

getting a clear audio stream. 

Packet loss 

Less than 1% 

 

When some packets do not arrive, there are 

gaps in the audio stream. Because voice is a 

real-time application, the missed packets will 

not be retransmitted.
