VOIP Recorder in Detail
After reading the feature list you may still have some questions on how VOIP Recorder works. This section provides some specific information on the mechanics of VOIP Recorder to help you understand how it will help you. There is a lot of technical information on this page which can generally be skipped. If you are not interested in the details, then go straight to the download.
Vonage™, like most digital telephone services, uses network protocols and formats known as SIP, RTP, and SDP. Phone calls using these protocols are called "VOIP" (Voice over IP) calls. The data for these protocols flow between your Vonage™ ATA and Vonage™ servers on the Internet. The ATA is the device you plug your phone into.
VOIP Recorder re-routes those digital telephone network packets so they flow through your computer on the way to and from the Vonage™ servers. VOIP recorder makes a copy of them as they pass through your computer for use in recording or Caller-ID notification.
The diagram shows the logical data flow when VOIP Recorder is active. Your computer remains connected to a standard home networking switch (wired or wireless) and the VOIP Recorder software takes care of re-routing the data for you.
A lot of people ask if this adds extra time to the network communication and, if so, is that a problem for call quality? The answer is that it adds very little time - typically less than 1 millisecond. This is not a problem at all because voice protocols are already very tolerant to much larger variances in the latency in between the clients and servers.
Two conditions must be met for VOIP Recorder to accomplish this routing:
This configuration is a very common way to setup the Vonage™ device and is a supported operational setup. Doing this not only allows you to use VOIP Recorder, it also places your telephone behind the firewall typically built into your home networking router. This gives you extra security. Some Internet Service Providers combine the Cable or DSL Modem with a home router. It is OK in those circumstances to connect the Vonage™ ATA directly to that all-in-one device as long as it is the same router your computer is connected to.
The phone call data always flows directly out the WAN port of the Vonage™ device. This port is generally blue and is sometimes called the Internet port. If that port is not connected to your Home Networking LAN, then VOIP recorder will never have an opportunity to capture the telephone data.
If your computer is turned off without shutting down VOIP Recorder the normal data flow directly between the Vonage™ ATA and servers will resume within a couple of minutes. Shutting down properly creates a seamless transition.
Very expensive enterprise grade LAN switches may contain a feature known as Dynamic Arp Inspection. This feature will have a problem interacting with the auto re-routing employed by VOIP Recorder. This is not a significant problem because these switches also have a feature known as Port Mirroring which can be used for call recording and Caller-ID pop-ups. These switches generally also have the ability to disable Dynamic Arp Inspection on a per port basis if necessary. There is no need to worry about this configuration for the vast majority of home, home office, and small business users as the switches generally used in those environments do not employ Dynamic Arp Inspection.
Recording of telephone calls is almost certainly regulated by your local laws. The laws governing the location where the other party is located may also be applicable. This software and website cannot provide legal advice. To obtain legal advice you should see a lawyer.
The Reporter's Committee for Freedom of the Press provides a good guide for getting started on your research. Often consent of one or both parties is a required condition for taping.
VOIP recorder provides two optional mechanisms to help in the establishment of consent.
First, VOIP recorder provides the configurable ability to insert a recording announcement into the beginning of a call. This announcement lets the caller know the call is being recorded and can establish consent if they stay on the line. The announcements can be configured to be heard by both parties, just one party, or no-one if consent is established in a different way or is not required.
VOIP Recorder also provides courtesy beep insertion functionality. These beeps are a short 175 milliseconds in duration and can be played as often as every 15 seconds. These beeps may be played in either direction (or none, or both!).
