Debugging Isdn Signaling; Verify An Incoming Call - Patton electronics SmartNode Series Software Configuration Manual

42 • VoIP debugging
A basic call from an ISDN terminal connected to your unit over SIP to another SIP gateway is thus an incom-
ing and outgoing call a the same time, from the context CS perspective: It comes in from ISDN and goes out over
SIP.

Verify an incoming call

Make sure an incoming call is entering correctly context CS. In this example, an ISDN terminal connected to
an ISDN port places a call. The port is in NET mode. The port is bound to a context CS interface named
TERMINAL. The debug output below shows a normal (working) call setup sequence.

Purpose
Prints all ISDN layer 3 signaling messages, and
call control related activity of the ISDN interface.
This is a good monitor to start with when debug-
ging ISDN.
Prints all errors occuring in ISDN call control and
ISDN datapath control. Always switch this monitor
on when debugging ISDN.
Prints operations on the ISDN part of the voice
data path. Use this monitor if you experience prob-
lems in the data path (no speech connectivity,
speech only in one direction). This monitor is not
needed to debug signaling.
Prints all errors occurring on the ISDN port (proto-
col stack layers 1 to 3). Always switch this monitor
on when debugging ISDN.
Logs in detail the operation on the ISDN port (pro-
tocol stack layers 1 to 3).
Shows the status of an ISDN port. Among others,
indicates the link state of that port.
Shows the status of an ISDN interface in context
CS (call control part of ISDN signaling). Shown
are all calls currently onging on the interface, with
their call states, signaling peers and voice data
path parameters.
name is the name of the ISDN interface. Use detail
5 for most verbose output.
