Hi Nabam, No charging/billing messages are defined by the SIP protocol, which implies that the application is responsible for the billing.
That is, SIP does not specify any methods for billing, and you are 'free to choose' and implement any application specific billing solution you need. Most often this is done in a pure SIP B2BUA as specified by Iñaki Baz Castillo. As an example you may consider, that the B2BUA (AS) will start a timer on receiving a 200 OK from callee and stops it when it gets a BYE. Now it has the call duration, hence you can charge based on the call duration.

I mean there must be some way to do billing on SIP call otherwise how service provider or vendor will get revenue. I understand that one way is by specified duration such as monthly, yearly etc. In IP-PBX based we might avoid billing but one is really required in IP-Centric SIP call server deployment.

Any call flow example would highly be appreciated. SIP is not "designed" for billing. Also billing is too much complex and wide to try to explain it in an unique way. Basically billing can be done in a gateway (which handles also the media), in a proxy (very very very vulnerable), in a pure SIP B2BUA (more reliable and secure than a proxy for billing)... There is no magic response. -- Iñaki Baz Castillo <i...@aliax.net> _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
