- Legacy Line Compatibility: Permits companies to mix 2 analog phone ports (FXS via an S2 module) and 2 PSTN landlines (FXO via an O2 module) to keep traditional fax machines and local trunks active.
- Cellular GSM/3G/4G Integration: Supports a dedicated mobile network expansion module, letting corporate systems execute low-cost routing over local SIM cards or back up data lines via cellular trunks.
