HI,

How can i got the SIP password if i have the following 

1- SIP USER which use in Digest Authorization 
2- realm name
3- nonce 
4- uri
5- response
6-cnonce
7- REGISTERED captured messages 

As i know this should be 

{HA1} ={MD5}{A1}={MD5}{username}{realm}{password} 
{HA2} ={MD5}{A2}={MD5}{method}:{digestURI}
response=MD5{HA1}{nonce}{HA2}

but
i can't find any free script or tool to get it and am working on , so 
is there any ideas how to break the SIP digest information leakage and 
the appropriate tool for this except immunity canvas ?
