[asterisk-users] Newbie question: how to proxy the *real* caller-id on find-me/follow-me

[Philip Prindeville]

I've got the following set up:

Someone calls into my PBX on a single number (via SIP trunk from my 
carrier), and the get a voice menu of extensions.

On one of the extensions, it rings a bunch of internal SIP hardphones, 
plus ringing my cellphone via a hairpin through the cairrier's SIP/PSTN 
gateway.

The issue is that my cellphone shows my PBX's number, not the original 
calling number.

My dialplan looks like:

[globals]
...
TRUNK=SIP/sip_proxy-out
CELL=${TRUNK}/208xxxyyyy
PHILIP=SIP/bedroom_1&SIP/office_2&SIP/kitchen_1&${CELL}

[incoming]
exten => s,1,Answer()
; sometimes signaling and media get out of sync on cell networks...
exten => s,n,Wait(0.75)
exten => s,n,Playback(main-menu)
exten => s,n(exten),Background(vm-enter-number-to-call)
exten => s,n,WaitExten(5)
exten => s,n(goodbye),Playback(vm-goodbye)
exten => s,n(end),Hangup

...
exten => 111,1,Macro(stdexten,111,${PHILIP})
exten => 111,n,Goto(s,exten)

exten => 112,1,Macro(stdexten,112,${REDFISH})
exten => 112,n,Goto(s,exten)

...
exten => i,1,Playback(pbx-invalid)
exten => i,n,Goto(s,exten)

exten => t,1,Goto(s,goodbye)

Ok, so far, so good.

The problem is that when we hit "Macro(stdexten,111,${PHILIP})" and it 
does the "Dial(${PHILIP})" which includes the 
SIP/sip_proxy-out/208xxxyyyy, 208xxxyyyy rings with my PBX's extension.

Oddly, the internal phones ring with outside caller's extension.

[sip_proxy-out]
type=peer
fromuser=208nnnmmmm
fromdomain=x.x.x.x
host=y.y.y.y
call-limit=5
nat=yes


So I'm not setting the callerid on the peer by default.  What am I 
missing?  Do I need to modify the stdexten macro to dial with the 'o' 
option?  Or can I set this explicitly with a 'Set' before calling the 
macro?  Or do I need to be missing with the RDNIS?

Oh, I'm running Asterisk 1.2.25...  (yes, I'll upgrade when AstLinux 
upgrades).

P.S. I tried adding "|o" to the end of the PHILIP variable, but this 
didn't seem to make a difference.
