Hi Christer,

Do you mean this section in 22.173:

It is quit raw, and I didn't see any further progress for this topic.

Thanks,

Gao

8.2.16  Reverse charging 
8.2.16.1        Definition
The reverse charging at communication set up time service allows the 
terminating party to be charged for the entire communication. Only usage 
based charges can be applied to the terminating party. The service shall 
be requested by the originating party at communication set up time. The 
terminating party must receive an explicit indication of a reverse charge 
communication request.
This service description is based on the service description described in 
[E-19].
8.2.16.2        Service interactions with other IMS supplementary services
None.
8.2.16.3        Interoperability with PSTN/ISDN

RE: [sipcore] Does SIP support "Reverse Charging" function?







Hi,

>I guess you(or ALU) would alos have reverse charging requirement for your 
deployed IMS network. Then, may us propose the requirement to the SA1 
group, and then, SIP extension work in IETF? 

The requirement already exists in SA1 (3GPP TS 22.173).

Regards,

Christer
