Hello friends, I have been looking for a guide or a paper that will describe the process to effectively secure a VoIP deployment but I have not succeed, I use the search in cisco.com but the only document thatmight seem to help was not avaiavle because the url was deleted. Also I'm interested in another document with the most common vulnerabilities on a VoIP deployment, If any one of you have one at hand it will be very appreciated. Thanks in advance.
