Buenas noches,
Tengo teléfonos del modelo T42G con versión de firmware, mi consulta es: ¿Que versiones de firmware tengo que instalar antes de instalar la ultima actualización
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.

How to Upgrade Firmware on Yealink IP Phones?

Hope this helps.
