[SR-Users] Calling ims charging function in route_failure

[Shane Harrison]

Hi all,

Using a technique Daniel mentioned in a previous post, I have removed the parser issue.  I called a separate route block from the failure_route block and call the Ro_CCR from there.

However my questions still remain as I don't really know how to determine if that Ro_CCR() is safe to call from there.  Documentation has some stern warnings :-)

Cheers
Shane
