How to Have SBC Directly Respond to Re-INVITE
Hello,
In the flow, the left side is the SIP server, and the right side connects to Cisco via E1 lines.
After 15 minutes into the call, Cisco sends a invite (re-INVITE?).
Currently, the SIP server cannot respond correctly, causing the call to drop. Is there a configuration that allows the SBC to directly respond to this re-INVITE?
Thanks
