The question is Can ISDN functionality be virtualized operated over an IP Packet Network (IPN)? How can modulation be virutalized? Is there a Linux ISDN-server OSS available? How hardening the ISDN-server? Which vulnerabilities still exist within ISDN-signalling?
Crime tends to take advantage of technologies detachements.
Happy to hear from you.
How are the two prioritized voice channels of 64 kbps tagged in the IPvX stream? In section 5.1.1 of layer 1 of the basic network user interface you find the details
https://
How are voice IP packets prioritized cross-layered (fixed, mobile, sat)?
Where is the ISDN expert on FF?
The CSP has to provide backend (IPN core IP network) an IP emulation. Does this mean that if the CSP does not know/want the two B-channels (voice) lose their ToS/QoS IPvX header flags?
Please help.
ISDN reaches back to SIGTRAN (old times). See here the PRI/BRI details

Obviously the signalling is for the CSP a problem as he needs a SIGTRAN converter
