Hi,

I would need help about how to go back a 7940 phone with MGCP firmware to be a 7940 skinny phone.

I don't know the 'Unlock Config' password on the MGCP phone configuration and I have tried to set up the option 66 and 150 in DHCP, but it seems not to work.

Please, cac someone provide me some guidance with this issue?

Thanks in advance for your help,

Juan Luis

What load version is MGCP and what version of SCCP are you trying to get to?

The following link describes the possible protocol/version upgrade scenarios available:
