I have a CALEA appliance from BearHill that I 'rent'. It has been in my network for years. I'm looking for other alternative solutions for CALEA compliance with a small ISP. It looks like OpenCalea is a dead project. What is everyone else using?
My current solution is $1k/month and I rarely get subpoenas, I've never had a wiretap one.
My ISP network is a mix of Cisco and Juniper gear. I have a couple GigE connections to my upstreams and push 300-400mbps through the network.
I would think that wireshark pcap files would be enough
