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

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

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 ?
