Summary:                    redirect to fax extension only after ring
Description: 
Sending fax over SIP using app_fax to 1.6.2.6. faxdetect=yes is set in
sip.conf.

extensions.conf:

[incoming]
exten => fax,1,NoOp(Fax Detected)  ;; the fax line
exten => fax,n,GoTo(incoming-fax,s,1)
exten => fax,n,Hangup()            ;; the fax machine

exten =>s,1,Answer()
exten =>s,n,Wait(100)
exten =>s,n,NoOp(" callerid: "${CALLERID(all)})
exten =>s,n,Dial(${House_Phones},60)
.......

But fax calls don't go to the fax extension until after one ring. 
As you can see I've increased Wait to 100. But the same thing happens
whether Wait is 4, 8 or 100. One ring on the House_Phones, then fax.

    -- Executing [s at incoming:1] Answer("SIP/side-sip-0000001d", "") in new
stack
    -- Executing [s at incoming:2] Wait("SIP/side-sip-0000001d", "100") in
new stack
    -- Executing [s at incoming:3] NoOp("SIP/side-sip-0000001d", "" callerid:
""asterisk" <asterisk>") in new stack
    -- Executing [s at incoming:4] Dial("SIP/side-sip-0000001d",
"DAHDI/g0,60") in new stack
    -- Called g0
    -- DAHDI/1-1 is ringing
  == Redirecting 'SIP/side-sip-0000001d' to fax extension
    -- Hungup 'DAHDI/1-1'
  == Spawn extension (incoming, fax, 1) exited non-zero on
'SIP/side-sip-0000001d'
    -- Executing [fax at incoming:1] NoOp("SIP/side-sip-0000001d", "Fax
Detected") in new stack
    -- Executing [fax at incoming:2] Goto("SIP/side-sip-0000001d",
"incoming-fax,s,1") in new stack

Wow, Wait(4.8) worked. How did you ever figure out 4.8? While it hardly
resolves the issue, it does make it work for me. 

Now if I can just get T38 faxing to work!
