### Description

```asn1
visdnSignalingCallingAddress OBJECT-TYPE
SYNTAX DisplayString
\-- ACCESS read-write
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The ISDN Address to be assigned to this signaling
channel. More specifically, this is the 'Calling Address
information element' as being passed to the switch
in outgoing call setup messages.

It can be an EAZ (1TR6), a calling number (DSS1, ETSI)
or any other number necessary to identify a signaling
interface. If there is no such number defined or required,
this is a zero length string. It is represented in
DisplayString form.

Incoming calls can also be identified by this number.
If the Directory Number, i.e. the Called Number in
incoming calls, is different to this number, the
visdnDirectoryTable has to be used to specify all
possible Directory Numbers.

The format of this information largely depends on the type
of switch or PBX the device is connected to. Therefore,
the detailed format of this information is not
specified and is implementation dependent.

If possible, the agent should implement this information
using the E.164 number format. In this case, the number
must start with '+'. Otherwise, IA5 number digits must
be used."

"ITU-T E.164, Q.931 chapter 4.5.10"
