[Asterisk-Users] Polycom IP600 dual ethernet port - bandwidth impact

[Rich Adamson]

FYI for anyone using the dual ethernet ports on a Polycom IP600.

I'm using a Polycom IP600 connected to an HP2524 10/100 switch, which 
has an asterisk box connected directly to it. No VLANs defined or in use.

Measured bandwidth:
  PC -> HP Switch -> Asterisk : actual throughput measured at 94.1 mbps.

  PC -> IP600 -> HP Switch -> Asterisk : actual measured at 91.9 mbps.

The second test (through the IP600) was conducted with a g711 
conversation in progress with absolutely no noticeable impact to the 
audio quality. The IP600 was running sip v1.5.2.0054 firmware.

The bandwidth tester (older version of NetIQ's QCheck) sent one megabyte 
  bursts of tcp traffic between the two endpoints using 1514 bytes packets.

The tests were run purely to document throughput of the phone when used 
with an attached PC.
