are sent to the PSTN:
Example: In the following example, all incoming calls from the mobile port trunk groups 26212 and 26213
are rejected with a busy signal:
8.3.3 REJECTING CALLS WITH ISDN BEARER CAPABILITY DATA
ISDN data calls can be handled differently from voice calls depending on the configuration of the call types DATA
or VOICE. This setting is especially interesting for VoIP or mobile calls:
MapAll<direct>=&<cause> <mode>
Example: In the following example, all ISDN data calls are rejected with the cause value AA (switching
equipment congestion). All calls with the prefix 0170 are routed to the mobile trunk group 26211
and all other calls are routed through VoIP:
8.3.4 SPECIFIC ROUTING OF DATA CALLS VIA VOIP
In the ISDN network, data calls have a special service type. When an ISDN PBX is connected to a VoIP network, it
must continue to work without any problems (e.g. PBX remote maintenance calls or ISDN terminal adapter). In the
case of VoIP, a specific RTP payload type is used: trp, ccd or gnx64.
Example: In the following example, two VoIP profiles are configured, so that all calls are routed, regardless
of whether they are data calls or voice over IP calls. The first one is for outgoing voice calls and
all calls from VoIP to ISDN. The second profile is exclusively for outgoing data calls, so that sig-
naling consists solely of clear mode in SDP:

Analog modem connections are not included in this configuration, as they generally
do not have a specified bearer capability.
