Key features
- Branch survivability: keeps full SIP voice service running locally when the WAN link to HQ goes down.
- RFC 3261 SIP Proxy + Registrar — registrar for SIP devices at the remote branch.
- Local Media Server — tones, announcements and conferencing; saves WAN bandwidth from central.
- Voice Mail integration — branch-side mailboxes that keep working without central reachability.
- Integrated Session Border Controller (SBC): stateful inspection firewall, NAT/PAT, VPN, protection.
- Branch SIP Trunking — direct ITSP connection on the branch side.
- 550 / 550 HA model: integrated PSTN Gateway + Analog Terminal Adapter (ATA).
- Six deployment scenarios: Proxy / Proxy ACD / SBC Proxy / Branch SBC / ATA / Gateway Only.
- Single network element management via Common Management Portal (CMP) — 'zero touch' maintenance.
- Scales to 6,000 registered user lines.
- Virtual appliance: hardware-independent VMware vSphere deployment for models without integrated gateway.
Typical applications
Multi-branch holding offices — connected to central OS Voice via SIP, local voice continues if WAN drops.
Hotel chain — branch guest rooms + reception SIP devices, external trunks via ITSP.
Bank branch — critical customer calls don't drop during WAN outage (survivability).
Hospital remote polyclinic — emergency line + central system integration.
Dealer network — small locations with SBC-secured SIP, gateway-only mode for PSTN.
