asterisk users - Mar 2014 - AMD with analog lines - DIALSTATUS empty

Hello,

I would like to use AMD on outgoing calls using analog line. I tested 
with SPA3102 and cisco2811 as gw and asterisk 1.8.26.1 as well as 11.8.1 
Other end is analog number behind another cisco/asterisk, also tested 
calling a mobile number with the same result.

What I did: dial is done like exten => s,n,Dial(SIP/<IP gw>/<dialed 
number>,,M(myMacro)), which tell Asterisk to execute myMacro when the 
call is answered by calling party.

[myMacro]

exten => s,1,NoOP(Executed when call is answered)
  same => n,AMD()
  same => n,NoOp(Dial status=${DIALSTATUS})
  same => n,NoOp(AMD status=${AMDSTATUS} cause=${AMDCAUSE})
  same => n,MacroExit()

Problem is that [myMacro] is executed as soon as the call is going out 
from the gw (cisco or linksys) and before called party answered. 
DIALSTATUS is empty (should be ANSWER), AMDSTATUS=NOTSURE and 
AMDCAUSE=TOOLONG-5000 which seems OK as DIALSTATUS isn't reliable.

The same dialplan using a SIP trunk is working as expected.

So question is, why, when using analog line, I dont get the right behavior.

Thanks for any hint

Analog lines don't have a reliable way to know when the far end actually
answers.  Polarity
reversals could signal when the far end actually answers, but it isn't
normally available or
standardized.  Thus, the line is considered answered when dialing is
complete.
