All telecoms switching and routing equipment is snooping equipment
It's the nature of the beast I'm afraid. All switches come with a facility to monitor calls. The billing records produced by all switches can be taken by any government agency and mined for potentially useful information. Any short message service centre can be configured to keep a log of messages and their content. As for IP based routing equipment, well logs (ostensibly switched on for diagnostic purposes) can certainly capture places visited, conversations initiated and so on. The actual content is a bit harder with IP due to volume.
