VoIP channels
The number of available VoIP channels depends on the codecs used, defined by the set VoIP operation mode. The overviews below give information about possible combinations.
COMtrexx Business:Installed and configured 4FXS modules reduce the available VoIP operation modes and therefore also the maximum number of available VoIP channels. If a 4FXS module has been added at a later point of time so that the current VoIP operating mode is not possible, the VoIP operation mode has to be changed manually.
