well, who says that the example and passwords are correct on that page? It could be just a tutorial without a working hash/password.
Indeed, I tried with sipcrack and it doesn't crack with that password.
What is also suspicious is the hashes dc59445f8ef78a615a2ad4... vs dc59495f8eb78a605a2ad5... It really seems that this is a modified hash or something like this. Hashes generally are not that similar even if you would be very lucky you wouldn't end up with 2 hashes that look almost the same.
I would recommend to just do your own capture or use some examples where at least by following the tutorial you would also get a postive hit (in this case the sipcrack run does not work, at least not on my stystem).
