The Tunnel technology has been developed by VoipSwitch in order to enable making and receiving VoIP calls for users who are behind firewalls that block VoIP traffic, especially in countries like UAE, Oman and some other which have recently decided to delegalize internet telephony.

The Tunnel is part of the main package thus it’s granted with the purchase of VoipSwitch main platform.

The Tunnel reduces the number of ports needed for VoIP communication to only one. The VoIP Tunnel is compatible with any hardware or software SIP clients. It is also embedded in our softphones, both SIPLink and Video PC Softphone.

The communication between the client and the Tunnel Server can be either in TCP or UDP protocol and can use any port (to be specified by VoipSwitch administrator).
