7 Signaling and routing features
VoIPBox BRI Version 18.0.002 Page 180
7.3.3 Rejecting calls with ISDN bearer capability data
ISDN data calls can be handled differently from voice calls de-
pending on the configuration of the call types DATA or VOICE.
This setting is especially interesting for VoIP or mobile calls:
MapAll<direct>=&<cause> <mode>
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.
7.3.4 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.
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
Analog modem connections are not included in this con-
figuration, as they generally do not have a specified bear-
er capability.
