MWI on SIP Phone during SRST: an open bug yet to solve!

Well, I discovered it when was trying to solve a issue on IEOC forum. MWI on SCCP phones works without any issue, but for SIP? It’s still a bug (bug id CSCta76151) on 12.4T trends IOS series.

Cisco Bug Toolkit can really save some of your precious time if you search for the bug rather than getting panic and googling and googling when anything not working.

Decryption of IOS Passwords/Secrets: an IOS method!

It’s very regular issue who works for support team, who have the router/IOS configuration files but can’t retrieve the password. Even I don’t know how you faced the issue guys but it was very regular headache for me until i didn’t know this simple method to decrypt the IOS secrets! No, its by any tool or by any code on C/C++! It’s from the IOS itself!! Now let’s see how it works….

Let’s the username/password string we got from IOS is:

‘username cisco password 7 0822455D0A16554745’

Now we need to find out what’s the actual password encrypted to ‘7 0822455D0A16554745’. Now we will need to take help from another router and follow the command chains like below:

R3#conf t
R3(config)#key chain ?
WORD Key-chain name

R3(config)#key chain decryption
R3(config-keychain)#key ?
<0-2147483647> Key identifier

R3(config-keychain)#key 1
R3(config-keychain-key)#key-string 7 0822455D0A16554745
R3(config-keychain-key)#do sh key chain decryption
Key-chain decrypt:
key 1 — text “cisco007”
accept lifetime (always valid) – (always valid) [valid now]
send lifetime (always valid) – (always valid) [valid now]
R3(config-keychain-key)#

So the actual secret was ‘cisco007’! 🙂
