Interoperability Notes

ICE-Lite impacts the following on the SBC 1000/2000 and SBC SWe LiteEdge.

SBC Feature	Supports	Does not Support
ICE Restarts The Spacevars 0 product does not support ICE restarts as required to change the destination of a data stream.
TURN server operation The Spacevars 0 product does not support TURN server operation. With some topologies the ICE protocol may require use of a TURN server to traverse a NAT on the Spacevars 0 product side; the the SBC is unable to establish connectivity between endpoints in such scenarios.
STUN Server Operation with Full ICE Mode Only The Spacevars 0 product supports STUN server operation for gathering candidates only when the ICE Mode is Full, not with the Lite ICE Mode.
Internet Connection Using UDP Candidate As an ICE-Lite agent (controlled agent only) , the Spacevars 0 product connects to the public Internet using a single host UDP candidate.
RTP and RTCP Media The Spacevars 0 product supports Real-Time Transport Protocol (RTP) and Real-Time Transport Control Protocol (RTCP) as two separate components for each candidate unless data streams are multiplexed on the same port.
Ports for RTP and RTCP The Spacevars 0 product supports sending and receiving RTP and RTCP on nonconsecutive ports for the Spacevars 0 longproduct and the Spacevars 0 product3 .
IPv4 Support Only As an ICE-Lite agent, the Spacevars 0 product connects to the public IP address using a single IPv4 address.
