[asterisk-users] How to retrieve a phone number from call forwarding?

[Soonthorn Ativanichayaphong]

Hi,

I'm very new to Asterisk and I have the following scenario.

1. Let's say I have a number of 1-222-222-2222 from my SIP service provider
(VoicePulse).
2. I point my phone, Verizon wireless cellphone (1-111-111-1111), voicemail
to the number provided by SIP service provider (1-222-222-2222).
3. I use another phone (1-333-333-333) to call 1-111-111-1111 and leave a
voicemail message.

Within my Asterisk console , I can see a caller id of 1-333-333-333 and the
number provided by SIP service provider (1-222-222-2222).
However, I couldn't figure out how to get the number the caller dialed (
1-111-111-1111).  Is there a way to retrieve the number the caller dialed
(i.e. 1-111-1111) in this scenario?

Note that as far as I know the carrier (e.g Verizon wireless) should pass on
those information. I see many companies that provide voicemail to email
services. They seem to be able to retrieve those information.
Is there a way to confirm that my SIP service provide does actually pass on
those information?

Here is what I have in extensions.conf to test this scenario

exten => _XX.,1,NoOp(Call received from VoicePulse)
exten => _XX.,n,Log(INFO|Caller ID Number: ${CALLERID(num)})
exten => _XX.,n,Answer()
exten => _XX.,n,DumpChan()
exten => _XX.,n,VoiceMail(101 at default,u)

Here is what I see on the console.
