[Asterisk-Users] more DIALSTATUS/HANGUPSTATUS woes with IAX2

[Andrew Kohlsmith]

Phone - TDM430P - home* - IAX2 - office* - PRI - Telco

I dial a busy number from the Phone.

Home* shows this in the CLI:

    -- Executing Macro("Zap/1-1", "dial-wu|2922004") in new stack
    -- Executing Dial("Zap/1-1", "IAX2/andrew at wu-ast/2922004||g") in new stack
    -- Called andrew at wu-ast/2922004
    -- Call accepted by wu-ast (format gsm)
    -- Format for call is gsm
    -- IAX2/wu-ast/1 is busy
    -- Hungup 'IAX2/wu-ast/1'
  == Everyone is busy/congested at this time
    -- Executing NoOp("Zap/1-1", "HANGUPCAUSE is 0 and DIALSTATUS is 
CHANUNAVAIL") in new stack

**WHY** is DIALSTATUS set to CHANUNAVAIL instead of BUSY?  Is the BUSY 
DIALSTATUS ever used??  How can I indicate that the line is busy if I can't 
detect when it's busy?!

Frustrated,
