OpenVox ATA gateways provide 2, 4, and 8 FXS options for analog phone and fax access, helping buyers narrow models first by port count, uplink class, and deployment footprint.
OpenVox ATA gateways help organizations keep analog phones, fax devices, and service lines in operation while moving call control into IPPBX, hosted PBX, or SIP server environments. The result is a cleaner migration path, lower endpoint replacement cost, and less disruption to existing voice workflows.
Start with the ATA model that matches your live analog endpoint count, cabinet footprint, and uplink preference.
2 FXS for compact analog points
Use iAG200 for front desks, small offices, and two-line analog retention where the smallest footprint is enough.
4 FXS for small branch rooms
Use iAG400 when a branch room or wall cabinet needs a few more analog phones or fax lines without stepping up to 8 ports.
8 FXS for standard analog consolidation
Use iAG801 when one gateway should consolidate a larger analog handset or fax group with standard 8-port density.
8 FXS for refreshed voice and fax access
Use iAG802 when the site still needs 8 FXS ports but prefers the newer hardware path for voice and fax refresh projects.
OpenVox iAG ATA gateways share the same SIP-to-FXS access architecture, fax support path, and remote maintenance framework across the full range.
Keep analog phones, fax devices, and service lines working while SIP takes over call control upstream.
Plan voice continuity and fax handling the same way across the whole ATA range before rollout.
Fast Ethernet stays on the 2 and 4 port models, while Gigabit uplinks sit on the 8 port models.
Support rollout and fault isolation with encrypted web access, SSH, SNMP monitoring, logs, configuration backup, firmware upgrade, and packet capture.
Before ordering, confirm the analog endpoint count, uplink type, fax handling requirements, and maintenance method for the target site.
