Minimum Req’s – ShoreTel B

Parameter Requirement
Bandwidth With ADPCM and no RTP Header Compression: 52 Kbps per call
With G.729a and no RTP Header Compression: 26 Kbps per call
With G.711 and no RTP Header Compression: 82 Kbps per call
NOTE: If your network uses VPN, bandwidth use is affected.
Latency and jitter for toll Quality < 100 msecs total
100 msecs less 42 msecs allocated for the Shoreline system yields a 58 msec budget for the network.
When G.729a encoding is used, 100 msecs less 62 msecs allocations for the Shoreline system yields a 38 msec budget for the network.
Latency and jitter for acceptable Quality < 150 msecs total
150 msecs less 42 msecs allocated for the Shoreline4 system yields a 108 msec budget for the network.
When G.729a encoding is used, 150 msecs less 62 msecs allocated for the Shoreline4 system yields an 88 msec budget for the network.
Packet loss < 1% for voice calls, and no packet loss for fax and modem calls
