Tracking the call path is even then possible if the call is routed two or more times through the Virtual
Loop:
The SMDR will then show like this:

Here, the call passes twice through the Virtual Loopback, the first time using trunk #5, the second time
using trunk #6. Note the reverse order which is the result of the called party clearing the call, so that the
last leg is printed first. The opposite order occurs if the calling party clears first:

This special tagging applies anytime Virtual Loop ports are used. If an extension uses a Virtual Loop
T-point to dial 'out', this port is tagged in the SMDR report accordingly; as well the associated S-point.
The same applies if internal SMDR is enabled and the S-point is called. Then, the S-point is printed as
tagged associated T-point. Here is an example of an external call being routed through the T-point of the
Virtual Loop:
