• Action code values:
—
0 — reserved
— 1 — UNIStim Hello (currently this type is the only valid choice)
— 2 to 254 — reserved
— 255 — reserved
•
iii.jjj.kkk.lll are ASCII-encoded decimal numbers representing
the IP address of the server. They do not need to be three digits long
because the . and : delimiters guarantee parsing. For example, ’001’,
’01’, and ’1’ would be parsed correctly and interpreted as value 0x01
internal to the IP Phone. These fields must be no longer than three
digits.
•
ppppp is the port number in ASCII-encoded decimal. It does not need
to be five digits long as the : and , delimiters guarantee parsing. For
example, ’05001’, ’5001’, ’1’, ’00001’ would be parsed correctly and
accepted as correct. The valid range is 0 to 65535 (stored internally in
the IP Phone as hexadecimal in range 0 to 0xFFFF). This field must be
no longer than five digits.
•
In all cases, the ASCII-encoded numbers are treated as decimal values
and all leading zeros are ignored. Specifically, a leading zero does
not change the interpretation of the value to be OCTAL-encoded. For
example, 0021, 021, and 21 are all parsed and interpreted as decimal
21.
•
When using the Full DHCP option, the XAS IP address can be
provided. To do this, append the XAS IP address and port to the Nortel
DHCP option currently used to specify the first and second server
IP address, ports, and retry and action codes. For Graphical XAS
(GXAS), the action code (aaa) and retry count (rrr) must be appended.
For Text XAS, it is not necessary to append these values.
The format of the exchange application server IP address and port is:
iii.jjj.kkk.lll:ppppp,aaa,rrr
The XAS port action code (aaa) byte values are:
— 1=Graphical XAS
— 0=Text XAS
The port field is processed if GXAS is selected, but ignored for Text
XAS (the fixed text port is used). XAS always uses port 5000.
If the XAS port action code (aaa) byte value is 0 (Text XAS), then the
port action code and retry count fields are not required. If the XAS port
action code (aaa) byte value is 1 (Graphical XAS), then the port action
code and retry count fields are not optional and must be included in the
configuration string.
