[SIPForum-discussion] How is SIP billed ?

Thu Apr 23 17:05:13 UTC 2009

Hello

In 3GPP, there are recommendation for indication of SIP bearers to the
GW/GGSN, using which the GW can initiate the billing to the charging
system (if required).  

Refer to 3GPP site 29.228, 29.214,29.212, 23.203 release 8 for details.

Thanks & Regards
Abhishek
