With the choice of five types, the IP Phone 2004 can operate in environments where the
initial choice is already in use by a different vendor. Select only one Type byte.
• Length (1 octet): variable—depends on message content
• Data (Length octets): ASCII-based—format Nortel-i2004-
A,iii.jjj.kkk.lll:ppppp,aaa,rrr;iii.jjj.kkk.lll:pppp,aaa,rrr
- Nortel-i2004-A uniquely identifies this as the Avaya option. Additionally, the -A
signifies this version of this specification. For example, future enhancements could
use -B.
- ASCII (,)—separates the fields
- ASCII (;)—separates the primary from secondary server info
- ASCII (.)—signals the end of the structure
- iii.jjj.kkk.lll:ppppp—identifies the IP:port for the server (ASCII-encoded decimal)
- aaa—identifies the action for the server (ASCII-encoded decimal, range 0 to 255)
- rrr—identifies the retry count for the server (ASCII-encoded decimal, range 0 to 255)
This string can be NULL terminated although the NULL is not required for parsing.
Notes:
1. aaa and rrr are ASCII-encoded decimal numbers with a range of 0 to 255. They

guarantee parsing. For example, '001', '01', and '1' are all parsed correctly and

longer than three digits each.
