Choosing a VoIP gateway or ATA
- FXS adapters and gateways: connect analog phones and fax machines to a SIP system, from one port on a desktop ATA to 48 ports in a rack unit.
- FXO gateways: connect existing PSTN lines to a SIP PBX.
- E1/T1 digital gateways: connect digital trunks to a SIP network.
Count the analog devices or lines in use today and choose a port count with spare capacity. For fax, look for T.38 support, and for a line that works during a power cut, look for an FXS port with lifeline. Check whether the unit takes PoE or an external adapter, and whether it can be managed centrally across several sites.
