EQUIREMENTS
The BROADBAND MODULE and BROADBAND MODULE PLUS support two different codecs,
each with different bandwidth requirements. In addition to the bandwidth used by a codec, there
is also an overhead imposed by the various protocols used in transporting the IP packets as well
as signalling. When this is taken into account, the actual bandwidth required for each codec
increases significantly.
In order to ensure good voice quality, it is recommended that the following bandwidth is
available on the broadband connection for IP trunks and extensions
