I have been struggling here lately on the topic of how to properly Secure my Voice Network. I heard the PodCast on the ASA implementation and have read that is the way to go. However the how is always left out.... I think a segment on this would be great.
Can you explain in more detail how the ASA 5500 is implemented in the CUCM World. Voice Security is starting to be a reoccurring theme, but I am not finding much information pertaining to the Cisco Recommended Procedures or How tos (if you will.)
For Example:What type of ASA is required for what level? When I have a HQ of 2000 Phones and remote sites also with 1000....what should be used at the locations? Is there a Matrix of some sort?
How is it implemented (obviously at the network level) but how is the CUCM connected..... via IPSEC with the ASA?
Is there an SRND for a ASA Voice environment?
Obviously due to the TLS Proxy the ASA is very attractive, but what are the ups and downs compared to GetVPN?
For many people dealing with Firewalls and ASA's on a daily basis these questions might seem a little basic, but for people coming from the "Voice" Unified Communications Area there are a lot of things left unsaid. Unfortunately, when installing a CUCM Cluster and the Customer wants a Secure Voice Network.... they do not understand that this is more network security than voice, and it is up to us to magically come up with the answer.
This topic of Voice Security is becoming the number 1 issue with large companies today and the only official statement that I find states that we should use the ASA's. Great.... but how?
Thanks
