TelSIP is a SIP-based Voice-over-IP communication technology developed in Europe. The network is completely private as no account needs to be opened to access the network.

Requirements for network is a TelSIP Phone that comes with a TelSIP number already pre-assigned. Mobility and ease of use are the trademarks of TelSIP. TelSIP Phone works through any Internet connection, including 56K modems without any degrade in audio quality.

As of 31st August 2007, the TelSIP network has closed down.

[edit] TelNEURO Technology

PC-based SIP VoIP solutions generally have problems with firewall traversal. The TelSIP product line boasts its user-friendliness because of the TelNEURO technology, developed applying the most advanced neuronal network algorithmic (Artificial Intelligence main motor) to the multiplicity of NAT scenarios and implementations deployed all over the Internet. As a result of this research, the final TelNEURO smart NAT traversal approach is an inventive, efficient and effective firewall traversal solution.

TelNEURO minimizes the possibility of an unsuccessful firewall traversal situation that will require a configuration setup from the user side, and helps TelSIP automatically configure itself within milliseconds.

Some of the most critical issues that the TelNEURO technology has overcome are:

  1. IEEE 802.11 wireless networks. One of the most complex scenarios for WiFi VoIP connectivity is a two NAT network connection both with port-restricted NAT implementations. This TelNEURO advantage allows TelSIP users to place and receive calls from Notebooks connected to WiFi 802.11 wireless networks at airports, hotels, business centers, etc.
  2. Residential and small enterprise full-cone NAT firewalls. Those are the majority of home and middle-size office used NAT firewall deployments. TelNEURO goes through them with no need of system administrator configuration at all.
  3. Big Corporation's symmetric firewall/NAT. TelNEURO analyzes the symmetric behavior and chooses the right approach to establish a successful TelSIP communication. If TelNEURO detects that the firewall blocks all connections, TelNEURO itself will change its behavior and use the resources available in the net allowing TelSIP to establish in and out communications through the network.
