Hi all .
I have a concern. here I would like to update my Nec SL1100 v7.21 each time I receive this message (Firmware update cannot proceed because there is not enough free space.)
could you help me .
second point: I can neither receive a call on the line nor make an outgoing call as soon as I pick up it hangs up automatically
