Here is dialplan copied from extensions.conf.sample:

[macro-page];

exten => s,1,ChanIsAvail(${ARG1},s)                     ; j is for Jump
and s is for ANY call
exten => s,n,GoToIf($[ ${AVAILSTATUS} = 1 ]?autoanswer:fail)
exten => s,n(autoanswer),Set(_ALERT_INFO="RA")                  ; This is
for the PolyComs
exten => s,n,SIPAddHeader(Call-Info: Answer-After=0)    ; This is for the
Grandstream, Snoms, and Others
exten => s,n,NoOp()                                     ; Add others here

---------------------------------------------------------------------- 
changed the following line 
if ((inuse <= 1) && (tempchan = ast_request(tech, chan->nativeformats,
number, &status)))
to
if ((inuse > 1) && (tempchan = ast_request(tech, chan->nativeformats,
number, &status)))

seems fixed the problem
