Hello list.
I'm wondering how the "Call Forward" works in OpenSer.
As the diversion module example shows, a INVITE message is catch in
the SIP Server, the the R-URI is changed for the forwarded number:
INVITE sip:bob at sip.org SIP/2.0
Via: SIP/2.0/UDP 1.2.3.4:5060
From: "mark" <sip:mark at sip.org>;tag=ldgheoihege
To: "Bob" <sip:bob at sip.org>
Call-ID: adgasdkgjhkjha at 1.2.3.4
CSeq: 3 INVITE
Contact: <sip:mark at 1.2.3.4>
Content-Length: 0
The INVITE message is diverted and the new destination is sip:alice at sip.org
:
INVITE sip:alice at sip.org SIP/2.0
Via: SIP/2.0/UDP 5.6.7.8:5060
Via: SIP/2.0/UDP 1.2.3.4:5060
From: "mark" <sip:mark at sip.org>;tag=ldgheoihege
To: "Bob" <sip:bob at sip.org>
Call-ID: adgasdkgjhkjha at 1.2.3.4
CSeq: 3 INVITE
Diversion: <sip:bob at sip.org>;reason=user-busy
Contact: <sip:mark at 1.2.3.4>
Content-Length: 0
How this new INVITE is reflected in the Start and Stop message for the
accounting ??. How the "divertor" is billed ?
Hope that someone can clarify this.
Regards,
Ricardo Martinez
