Hi Eleni,

ETC implies that the 3GPP OCS (HPLMN) is connecting to a gsmSRF/assisting_gsmSSF.
Looks like it is trying to setup a session to send an announcement menu.

I would ask the HPLMN operator to explain their current setup with their OCS solution.

Note: OCS: Online Charging System that is used for Realtime Charging for Voice (CAP V2 / V3) and Data (Gy).

Thanks Eleni,

CAP V2 has been around for a long time. The Call Flow Use Case(s) is well established for Telephony between the
gsmSSF and the gsmSCF / SDF entities.

For your "converged" Charging Prepaid platform for Voice / Data I am assuming that CAP V3 (GPRS Data) and CAP V2 is integrated onto the same platform (gsmSCF / SCP / SDF). Next step is now to look at the Tariff Plan configuration and the "buckets" that have been configured for Voice, Voice-Roaming, Data, SMS, etc..

Mediated CDRs will also help to understand what has happened with the Voice session.

Thanks for your answer

we and vplmn network support cap version2 and also

i change the camel data to msisdn number and prepaid platform is configured to
receive calls for recharge (for vplmn network)

i took the same result

before and after call credit is the same

Hi Eleni,

Any updates?

Did you check if you have Call-Control (CC) with your version of CAP V3. Assume that the configuration you have is that you will use CC your deployed MSC/VLR/gsmSSF. For GPRS, the gprsSSF will be used for pure data sessions.

For cAP V3 there is a relationship between the gprsSSF (SGSN)and the gsmSCF (SCP). This is different from the Call Control that is used to control Voice / Telephony. Check that your CAMEL node is equipped, i.e.
configured, for CAP V3 Call Control. Maybe you just have a data License implemented that
allows you to use CAP V3 for pure GPRS sessions.
