Hi Guys, in my company will make the VoIP. The solution that we want do is "full IP phones". In Other terms, we don't want have the PBX central!! In my organitazion, there is a firewall that we protect of the unauthorized access. The location of the firewall is in Germany (Emea). The location where we want make VoIP is in Rome. My question it is, how can i protect my Data network of the possibile access from Voice Network? Do i have to insert an other Firewall in Rome? It is enough that IP Phone and the PC for every user are in two different VLAN ? Regards, Carmelo P.S. Are there books that explain the security for VoIP? _________________________________ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
