Abstract
A method for tracing communications includes receiving trace criteria from a first remote element and determining whether a call signaling message matches the trace criteria. The method includes attaching a trace tag to the call signaling message, if the call signaling message matches the trace criteria. The method further includes transmitting the call signaling message to a second remote element.
