Connectivity to: • IP-PSTN
gateway • IP/PBX • Direct SIP • SIP trunk
A/V Edge – ICE: STUN/TCP:443, STUN/UDP:3478
Access Edge - SIP/TLS:443
A/V Edge – SRTP:443,3478,[TCP:50,000-59,999]
SRTP consists of two unidirectional streams. RTCP traffic piggy backs on the SRTP stream. Media codec varies per workload:- RTAudio- G.711- Siren- G.722
TCP:443 must be open inbound.
UDP:3478 must be open both inbound and outbound.

For federation, SBA connects directly with Director. If no Director is available, federation traffic goes directly to

Network Quality Considerations
Delay / Latency
Packet Loss
Jitter
Total two way delay below 150ms
For Lync limit to < 10 % loss traditional VoIP < 1 % loss
Limit jitter to < 30ms
