Buenas noches,
Tengo teléfonos del modelo T42G con versión de firmware 2.72.0.36, mi consulta es: ¿Que versiones de firmware tengo que instalar antes de instalar la ultima actualización 2.73.0.50.zip?.
Gracias de antemano
Buenas dias filomon,

Firmware 2.x.x.x belongs to the Yealink SIP-T28P and not to the SIP-T42G IP Phone.

Yes, it is possible to flash the firmware directly to the latest on.
