[cisco-voip] Some Noob questions about a new VoIP deployment

[Robert Holtz]

We are in the process of rolling out a Cisco VoIP network and there have been quite a few concerns expressed in regards to security.

We're using VACL's on our code 6509 switches to stop IP data VLAN ranges from entering the VoIP VLAN but it would appear that the program named "VoIP Hopper" would allow us to bypass and VACL.  I have yet to use VoIP Hopper but will attempt it some time soon.  Has anyone used this product to jump through a VACL?

Our next concern is QoS and what are some good open source tools to generate traffic to trigger the QoS queuing mechanisms.  All of our gear is gigabit Ethernet so I'm thinking that I won't be able to generate the level of traffic I need without multiple machines.  Promising tools so far look like "BitTwist" and "D-ITG".  Does anyone have any recommendations for these types of tools?

Thanks,
