Hi, Your questin is quite difficult to answer because depend on your country laws. About public network, I think you are concern about TDM service (PSTN). Well, as always, some stuff are not considered by the people who made some laws. Well, in my country customer are encouraged to deploy cross-systems. For example, PIN number is set by internet (where you can implement all crypting available). By phone in TDM no crypting, ( and by VoIP you have to implement SIPS and SRTP, TLS at least) then very strong set of questions/answer to do a positive verification of the caller. Of course, where you have to put encryption and security is inside of your systems, and deploy a good system control to control and manage your sensible data. Take a look this links: http://wiki.linuxwall.info/doku.php/en:ressources:dossiers:voip:tls_sips_rtp... and http://www.vadese.org/files/upload/Best_practices_VoIP_en_v20.pdf I hope this helps On 12/19/2011 7:22 AM, Avi Marcus wrote:
I'm planning on an IVR to accept credit card information for signing up and renewal of my services. Regarding fraud, I'm going to require at minimum a recording of name, who they are, or something or an actual live call.
But for PCI compliance.. this says https://www.pcisecuritystandards.org/documents/protecting_telephone-based_pa... on page 9:
Call centers will need to ensure that transmission of cardholder data across public networks is encrypted. This is part of PCI DSS Requirement 4 and includes:
* ...
* *Voice or data streams over Voice over IP (VoIP) telephone systems, whenever sent over an open or public network. Note that only those consumer or enterprise VoIP systems that provide strong cryptography should be used. *
* Requiring agents to use analog telephone lines when a VoIP telephone system does not provide strong cryptography.
I'm doing dtmf, not voice, but I can't imagine that's LESS strict.
I haven't really heard of any end-to-end encrypted origination lines. Is this guideline ignored? How do people deal with this? Does someone have T1 lines and offers encryption for origination...?
