VoIP with e2e

    Benefits

  • EFFICIENT TRANSIT through routers.
  • Bandwidth Traffic NOT hosted by Operator.

G3T's patented e2e Technology enables the direct communication set-up between two IP devices over the internet, regardless of whether or not those devices are located behind routers. This means that the Service Provider does NOT have to host any of the IP bandwidth traffic whether it be voice, video, images, music or any other content.

e2e Technology is essentially a lightweight IP signalling protocol which is available as a bolt-on Server Software, and used together with e2e client software by the IP device.

This has successfully been applied to internet telephony (VoIP) where non-hosted IP-to-IP calls can be made and available for the direct transmission of ANY media content; currently, voice, video, text, snapshot as well as voicemail and call forwarding. www.VePhone.net

Result:- Significant bandwidth cost savings on an increasing on-going basis.

[Note: the VePhone, available with a real UK telephone number, has full integration with worldwide Landline and mobile network for complete connectivity to traditional telephony]

VoIP with SBC's

    Cost Drawbacks

  • Session Border Controller's required.
  • Operator Hosts Bandwidth Traffic IN

    & BandwidthTraffic OUT.

A progressively more common situation globally is for access to the internet to be through the use of routers, whereby multiple devices can simultaneously access the internet. These routers apply network address translation to control the connectivity of multiple IP devices through one IP connection to the internet.

When the receiving IP device is located behind a router, then communication between the devices over the internet will invariably involve the Service (SIP) Provider hosting the bandwidth traffic for the whole duration of that IP-to-IP communication, through its own Session Border Controllers (SBC's).

In the past, this traffic essentially was simple low bandwidth voice traffic, however, vast bandwidth dependent content is becoming increasingly popular in the form of video, music, image and file transfer etc.

The current alternative methods that the SIP Service Providers may attempt to implement to avoid hosting the IP bandwidth traffic, is using STuN, TuRN or ICE protocols; however, all these have documented drawbacks either in terms of universal applicability or reliability.

    Drawback

  • Not work for Recipient behind Router.

When the receiving IP device is on a single IP address and NOT located behind a router, then communication is direct between the devices over the internet, without the Service (e.g. SIP) Provider hosting the bandwidth traffic.

This situation, though less likely, and arises when the receiving party is connected to the internet by a modem (and not behind a router). For the calling party it is not relevant whether they are behind a router or not.

As the Service Provider does not know the situation of the receiving party, it cannot guarantee avoiding having to host all the IP bandwidth traffic through its own infrastructure in order to ensure that the two parties communicate with each other.
