Assessing bandwidth – Example
B
andwidth required for Voice data
= Number of simultaneous calls x 2 x Required bandwidth for codecs (kbps)
= 16 x 2 x 80 = 2560kbps
Bandwidth required for Signalling
= Number of simultaneous calls x signalling bandwidth per call for SIP phones (kbps)
= 16 x 16 = 256kbps
Total required bandwidth
= Bandwidth required for Voice data (kbps) + Bandwidth required for signalling (kbps)
= 2560 + 256 = 2816kbps
Number of Extensions : 50
Extension Type : SIP Phone
Number of Simultaneous Calls : 16
CODEC : G.711
Packet Interval : 20ms
Bandwidth (4/4)
Slave Unit
Master Unit
IP Network
* In this example, Basic Ethernet frame, VPN headers, system control data, etc., are not considered.
