Claim Text:
1. A method comprising: receiving, by a microprocessor, a first global identifier that was generated based on an initiation of a first communication session in a first network, wherein the first global identifier is received during the initiation of the first communication session, wherein the first communication session is a communication session that occurs between the first network and a second network that are connected by a Public Switched Telephone Network (PSTN), wherein the first network and the second network are Session Initiation Protocol (SIP) or Web Real Communications (WebRTC) based; passing, by the microprocessor, the first global identifier as the first communication session progresses across the first network; generating, by the microprocessor, a second global identifier based on an initiation of the first communication session to the second network, wherein the second global identifier is used for the first communication session in the second network and the first global identifier is used for the first communication session in the first network; logging, by the microprocessor, the first communication session based on the first global identifier and the second global identifier in a communication log; and building, by the microprocessor, a map of the first communication session based on the first global identifier and the second global identifier by searching through the communication log for the first global identifier and the second global identifier, wherein the map of the first communication session is used for testing purposes.
