What is RSP and why use it?
- Used for sending CDR data over IP connections
- Introduced in Avaya™ Call Processing Release 9.5.
- Layer 5 (session layer) protocol, designed by Avaya
- Not required, but highly recommended
- Provides added reliability to the CDR data over IP
- Data labelling (sequence #) to prevent data loss
- Keep alive (timer + counter) for communication integrity
- If using IP without RSP
