[SR-Users] S-CSCF strange execution effects

[Carsten Bock]

Hi Flavio,

i need to update the example configuration files in order to work with
Diameter-Ro.
The Diameter operations are now all asnchronous, so the example for
the S-CSCF is no longer correct for the current Diameter-Ro-Module.
The Message processing stops after calling CCR_Ro() and is continued
in a separate route, once the Diameter-Response arrives.

An example, how the Call to CCR_Ro() should be constructed can be found here:
http://kamailio.org/docs/modules/devel/modules/ims_charging.html#idp1834808

I'll update the S-CSCF example later this week.

Kind regards,
Carsten
