[SR-Users] How S-CSCF route SIP INVITEs as per iFC ?

[Valentin Christoph]

Hi,

>>>>>> because it says in SAR that USER_DATA_ALREADY_EXISTS

This means the user data are not updated in S-CSCF. Please de-register first and then register again. This should help to get the new user data (with the added application server) to the S-CSCF instead of the old ones.

Routing according to iFC is quite complex. In principle it is done based on method, case, header content, body content.

Hope it helps
Christoph

I have added an Application Server in iFC and try to route one user to that Application server for testing But INVITE to that subscriber following the default iFC. I am using ng-voice HSS Server.

I have been trying to differentiate between iFCs for two different subscribers and unable to find the store location of SAA xml on S-CSCF and I am Unable to find xml file of required subscribers in wireshark traces as well because it says in SAR that USER_DATA_ALREADY_EXISTS and SAA didn't contain any XML file for that specific users.

Furthermore if you can describe SIP INVITEs routing mechanism of S-CSCF, on which params or SIP Headers S-CSCF route INVITEs to Application Servers according to iFC ?
