Summary:                    [feature request] Charge Number (ANI) is not
delivered through SIP
Description: 
With traditionnal telephony (SS7), we are using charge numbers for a clear
identification of the caller.

ANI transmission is mandatory, for urgency services as well as law
conformity.
Without ANI, then there is no possibility to hide the caller ID, neither
to manage billing for accounts having differents Caller-ID.

The caller ID can be hided or not by the sending party, but the charge
number cannot be hided.

Here is the mains fields we have in SS7 for number identification :

• Called Party Number
• Charge Number
• Originating Line Information Parameter
• Calling Party Number
• Original Called Number
• Redirecting Number


We tried this inside asterisk 1.4.21 :

[custom-ani-test]

exten => *889,1,Answer
exten => *889,n,Set(CALLERID(all)="Test CID"<050505>)
exten => *889,n,Set(CALLERID(ANI)=0325484565)
exten => *889,n,Dial(SIP/69,120)
exten => *889,n,Hangup

And we got this sip debug :

INVITE sip:69 at 192.168.200.60:5060;transport=udp SIP/2.0
Via: SIP/2.0/UDP 192.168.200.100:5060;branch=z9hG4bK1c475f7b;rport
From: "Test CID" <sip:050505 at 192.168.200.100>;tag=as538cf9f1
To: <sip:69 at 192.168.200.60:5060;transport=udp>
Contact: <sip:050505 at 192.168.200.100>


We can see that the ANI (charge number) as not been set. The ANI should be
present in the Contact: field . We can see that the Caller-ID number has
been duplicated here.


We should have :

INVITE sip:69 at 192.168.200.60:5060;transport=udp SIP/2.0
Via: SIP/2.0/UDP 192.168.200.100:5060;branch=z9hG4bK1c475f7b;rport
From: "Test CID" <sip:050505 at 192.168.200.100>;tag=as538cf9f1
To: <sip:69 at 192.168.200.60:5060;transport=udp>
Contact: <sip:0325484565 at 192.168.200.100>

It seems that ANI does not work over SIP.



Thanks for your listening.
