Cisco 1751 encrypted telnet password

[DManigo]

I just bought this router for VoIP use. I can access the router config through console or telnet. I would like to change the telnet password and VoIP passwords but they are encrypted.

ex. line vty 0 4
password 7 01040E0B5005091832
login
line vty 5 15
password 7 051C0E002A42411E0A

Is there anyway to de-crypt or disable encryption and change the passwords?
TIA

For disabling Type 7 password encryption...

no service password-encryption

Never solely rely on Type 7 password as your security defence.

whoknows is the password if you wanted to know and changing it is done in global config.

router#line vty 0 4
password XXXXXXXXXXX

line vty 5 15
password XXXXXXXXX

thats how i do it anyway
