We have a router terminating some PRI lines. These lines carry data and voice traffic. We have a requirement where we need to record voice going over this line. Generally we do voice recording in LAN using RSPAN and some recording tool like Witness or Nice etc.
In this case, because of certain customer limitations, we cannot do it in LAN. Is it possible to mirror traffic from one router port to another. Also can a standard tool like Witness etc can record such traffic mirrored over a router
