Figure 26-6: Adaptive versus Fixed Dejitter Buffer
The adaptive buffer automatically adapts to the network delay variation characteristics and in
general yields the best results. The manual fixed buffer is useful only if you have specific information
about your network, such as jitter period, etc. and should only used by experienced users.
Note:
In the adaptive dejitter buffer several more parameters could be configured, such as shrink-
speed or grow-step, etc. This parameters are described in more detail in Chapter 13, “Profile VoIP
Mode” in the SmartWare
Command Reference Guide
. The default values for these options should only
be overwritten if essential. Misconfiguration may lead to interoperability problems and loss of
service. Therefore it is strongly recommended that only experinced users change this parameters
