does not include a microphone and it does not support speaker
phone operation. The 3101SP and 3101 telephones each have 4
programmable Access buttons that are mapped by default as 2

Power over Ethernet (PoE), wideband audio, and G.729 compression.

for bandwidth efficiency.
New Attendant Console
Release 4.3 introduces the 3Com 3105 Attendant Console which
supports up to 100 station appearances using 50 Access buttons
and 4 Feature buttons. The 3105 Attendant Console supports Power
over Ethernet and 10/100 connectivity.
Support for G.729A/B
Release 4.3 introduces a new voice codec to the existing codec
set. G.729, an ITU standard, employs a sophisticated compression
technique that compresses the audio information to 8kbit/sec.
G.729A defines a method of compressing audio information. G.729
Appendix B (G.729B) defines a method of handling silence suppression.
New LabelMaker Utility
Release 4.3 introduces a new format for the NBX LabelMaker.
This new LabelMaker, a Windows .exe file that you can download
through the NBX NetSet utility, allows users and administrators
to create labels for any 3Com Telephone or Attendant Console
and then save the labels to a file.
