[OpenSIPS-Devel] Contribution: New function in siptrace module

[Dan Pascu]

The siptrace module already has the ability to record messages for a given 
user, by setting an AVP. That avp can be read from a property in the 
subscriber table (automatically loaded when the subscriber is loaded or 
by putting a subscriber in a group or by loading it explicitly from a 
different table). The real problem is not the inability to do this 
already, is the fact that is difficult to do it for all messages within 
dialog. By making the siptrace module work on top of the dialog module to 
automatically trigger tracing all messages within a dialog once the 
dialog was marked for tracing, this issue should be solved.

So what does you approach add in addition to the existing behavior that 
cannot be done already?
