The result is: a8f17d4b41ab8dab6c95d3c14e34a9e1
Next we need to evaluate the par called A2. We take:
The method type REGISTER
Using SIP protocol sip
Proxy IP from ini file 10.2.2.222
The equation to be evaluated:
REGISTER:sip:10.2.2.222.
The MD5 algorithm is run on this equation and stored for future usage.
The result is:a9a031cfddcb10d91c8e7b4926086f7e
The final stage:
The A1 result
The nonce from the proxy response: 11432d6bce58ddf02e3b5e1c77c010d2
The A2 result
The equation to be evaluated:
A1:11432d6bce58ddf02e3b5e1c77c010d2:A2.
The MD5 algorithm is run on this equation. The outcome of the calculation is the response
needed by the gateway to be able to register with the Proxy.
The response is: b9c45d0234a5abf5ddf5c704029b38cf
