Use and tips
The WP826 is aimed at users who spend the day away from a desk and do not want to recharge at noon: store managers, logistics staff, maintenance agents, hotel staff. The three SIP accounts let you receive, for example, the department line and the direct line on the same handset. Plan continuous Wi-Fi 6 coverage with roaming between access points. For a more economical 2-account model, see the WP816; for a rugged IP69K casing with lone worker alarms, the WP836.
