The device is operating behind
NAT (a STUN server is
available).
1 Verify that public IP address declared for the device
appears in the SDP of the SIP INVITE message as
assigned to the device by the STUN server.
2 Verify that the device is enabled to use a STUN server
('Enable STUN' parameter) and that its' IP address
('STUN Server Primary IP and/or 'STUN Server
Secondary IP' parameters) are defined (in the Web
interface's 'Application Settings' page - Web path SW
Ver. 5.2: Advanced Configuration menu > Network
Settings submenu > Application Settings; Web path SW
Ver. 5.4 and later: Configuration tab > Network Settings
menu > Application Settings).

The device's digit map plan is
not configured or incorrectly
configured.
Configure the digit mapping, using the ini file parameter
DigitMapping.
If the digit string (i.e., dialed number) matches one of the
patterns in the digit map, the device stops collecting digits
and establishes a call with the collected number.
The digit map pattern can contain up to 52 options, each
separated by a vertical bar (|). The maximum length of the
entire digit pattern is 152 characters.
Available notations:
[n-m]: Range of numbers (not letters).
. (single dot): Repeat digits until next notation (e.g., T.).
x: Any single digit.
T: Dial timeout (configured by the parameter
TimeBetweenDigits).
S: Immediately applies a specific rule that is part of a
general rule. For example, if your digit map includes a
general rule 'x.T' and a specific rule '11x', for the specific
rule to take precedence over the general rule, append 'S'
to the specific rule (i.e., '11xS').
An example of a digit map is shown below:
11xS|00T|[1-
7]xxx|8xxxxxxx|#xxxxxxx|*xx|91xxxxxxxxxx|9011x.T
In the example above, the last rule can apply to
