Some PBXs generate the tones itself before ISDN CONNECT message. With this
setting, the AS55X answers immediately with CONNECT and all tones and
announcements out of the GSM network are switched directly to the wired network.
Notice: Be careful if you use your gateway in public network which is not free
of charge. This choice will produce costs during the call-setup phase

Protocol option reject
If a SETUP from ISDN to the AS55X must be rejected (e.g. no GSM channel available),
this can be done in two ways.
The normal way is to reject the SETUP with RELEASE COMPLETE. But some PBXs
misinterpret this as error.
Alternatively the SETUP can be accepted and immediately disconnected.
In most cases the system will work fine with both settings. If the PBX is wanted to
reroute rejected calls, the success may depend on this protocol option.
Default value: Reject by RELEASE COMPLETE

Tone generation during call-setup
During the call-setup phase the AS55X normally generates tones or switches audio
from the GSM network to the ISDN interface. If the PBX should generate tones, it can
be set here.
This function is controlled by the progress indicator “in-band information available”,
but not all PBXs do interpret this indicator correctly.
Default value: ... by AS55X

Tone generation during call-termination
During the call-termination phase the AS55X normally generates a busy tone to the
ISDN interface. If the PBX is wanted to generate this tone, it can be set here.
This function is controlled by the progress indicator “in-band information available”,
but not all PBXs do interpret this indicator correctly.
