[Asterisk-Users] Want to automatically park call and have caller hear ring tones

[Joseph Tanner]

Here's the short of it.  I have an Asterisk 1.2.1 system setup to
handle both personal and business calls.  Now, the business callers
will hear music while on hold, so the default MOH needs to play
regular music.  Personal callers should hear rings, not music.  I have
this working except for one specific case.  If someone calls during
the day (we're night people), asterisk will not ring the phones. 
Often we'll be up before asterisk thinks we are, so we will miss quite
a few calls.

My solution was to have asterisk park the call for 15 seconds, send
the callerid information to a YAC listener on my laptop and our TiVo,
and I can pick up any phone and dial "4" to pick up the parked call. 
Works perfect, except parked callers hear music, not ringing.  To make
it a bit less confusing, I play a quick wav file saying to please hold
while your call is connected, which sounds rather impersonal (at least
for a personal call, it's fine for biz calls and is what I use there
too).

Is there a way to have a call parked, and have the caller hear the
default ringing tones, and not have to mess around with MOH? 
Currently I'm using ParkAndAnnounce, and just announcing it to
/dev/null (which it complains about, but it works).  Here's the
specific section of my extensions.conf file if anyone's curious:

[asleep]
exten => s/_931555XXXX,1,NoOp
exten => s/7205879978,1,NoOp
exten => s/4025179978,1,NoOp
exten => s,1,System(/bin/echo -n -e "'${CALLERIDNAME} ${CALLERIDNUM}'"
| nc -w 1 192.168.1.16 10629)
exten => s/_931555XXXX,2,NoOp
exten => s/7205879978,2,NoOp
exten => s/4025179978,2,NoOp
exten => s,2,System(/bin/echo -n -e "'${CALLERIDNAME} ${CALLERIDNUM}'"
| nc -w 1 192.168.1.19 10629)
exten => s,3,NoOp
exten => s,4,NoOp
exten => s/_731584XXXX,5,NoOp
exten => s/7205879978,5,NoOp
exten => s/4025179978,5,NoOp
exten => s,5,Playback(custom/pleasehold)
exten => s,6,ParkAndAnnounce(pbx-transfer:Parked|15|/dev/null|asleep,s,8)
exten => s,7,NoOp
exten => s,8,Playback(custom/voicemail)
exten => s,9,Voicemail(s1)
exten => s,10,Hangup
exten => s,107,NoOp
exten => s,108,Playback(custom/voicemail)
exten => s,109,Voicemail(s1)
exten => s,110,Hangup

Note that the call doesn't start here, rather it starts in another
context which checks the hours, then if it's in the middle of the day
it'll pass it off to the asleep context.  Here's what each line does. 
The first four lines are for s,1, basically if the callerid matches
one of the first three numbers, it does a NoOp.  Otherwise, it
performs the normal s,1 line which uses echo and nc (netcat) to send
the callerid information to my TiVo.  The s,2 lines are the same
thing, except it sends the info to my laptop (I changed the first
number to something generic, that's not what's actually in my config;
the other two are from calling cards that an annoying member of our
family uses, basically I'm ignoring all calls from them).  s,3 and s,4
are both NoOp in for future expansion.  s,5 gives the Please Hold
message, otherwise suddenly hearing music would be confusing.  s,6
parks the call for 15 seconds, after which time it returns to the
asleep context, line s,8.  s,7 is for future use.  s,8 plays back a
custom voicemail greeting, s,9 is for the caller to leave a voicemail
(vm doesn't give its own greeting, just starts with a beep).  s,10
hangs up.  s,107 is in case the parkandannounce doesn't work for
whatever reason, it's a NoOp which passes it to s,108 which as before
plays the vm greeting, s,109 is the actual voicemail, s,110 hangs up.

BTW, I just noticed I need to add those bad callerids between s,5 and
s,6, else they will be parked but not hear the please hold message (I
want those numbers to go straight to voicemail, I'll clean it up later
so I'm not repeating myself all the time).

Is there an easy way to do what I want, parking these calls
automatically and the caller just hears the normal ringing tone? 
Thanks!
