Peer-To-Peer (P2P) Calling

DBL Technology is now offering VoIP devices that can support global callings in peer-to-peer (P2P) configuration.  It is ideal for anyone who wants to setup a voice connection between two places without the support of an IP PBX / SIP Server.  Fixed public IP addresses are no longer required.  In addition, DBL offers models with GSM and PSTN terminations to extend IP callings to the GSM and PSTN networks.  Global calling can now be achieved easily without the traditional limitations.
