IMPORTANT:
The parameters mentioned above must have the
same value in all IPDA gateways (STMI2/4/STMIX/STMIY with regard to AMO CGWB
& NCUI2+/4 with regard to AMO STMIB). This avoids problems and a
common function across all systems is achieved!
With the introduction of the feature "Codec Switch on the fly" in
STMI4/STMIX/STMIY/NCUI4/OpenScape 4000 SoftGate setting RFCMOIP=NO in
AMO CGWB and AMO STMIB is the better option for fax/modem calls. Therefore,
the default value was changed from YES to NO. There is no necessity to
change the parameter in existing installations.
