Parameter
Permitted Values
Default
ptt.compatibilityMode
0 or 1
1
If 0, the PTT protocol behavior is not compatible with Spectralink handset models 8020/8030 or older. If 1, all PTT
protocol behavior is compatible with the older Spectralink handsets, even if some configuration parameters are
incompatible. For example, if this parameter is enabled and
ptt.codec
is set to G.722, the G.726QI codec will be
used for outgoing PTT audio to maintain compatibility.
If you are deploying Spectralink 87-Series handsets and need to maintain PTT compatibility, this parameter must
be set to 0 as the 87-Series handset does not support the G.726 codec.
