Remote and Centralized Management of SIM cards
Dynamic allocation of SIM cards
No need to replace / recharge SIM cards on-site
Hot swap of SIM Cards with no service interruptions
Example: GoIP with Remote SIM support will no longer require on-site SIM Card replacement or recharge. Management of a group of GoIPs can be achieved remotely, efficiently, and cost-effectively.

Free Global 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/Server. Fixed public IP addresses are no longer required; both devices can just be installed behind NAT. Traditionally, a P2P VoIP call occurs when two VoIP phones communicate directly over IP without IP PBXs between them. When the two VoIP phones are not located in the same network, fixed public IPs are required in order to achieve P2P Calling.

VoIP GSM Gateways

GoIP GSM Gateway bridges the GSM and the IP networks by enabling voice communications. It is installed on the Mobile SIM Card, you can register the GSM telephone on the VOIP Softswitch. it can be easily combined into arbitrary number of channels of Large Gateway Group. Low price, perfect sound quality and powerful function make GOIP GSM inevitable choice of system Integrators, traffic Business and soft switch Manufacturers.

Cross-Network Gateways

The fundamental of RoIP（Radio over IP）technology is to convert the audio and PTT signals in a radio terminal into IP packets and then transmit the data via the IP networks. The challenge in this technology is to insure that the audio is transmitted in real time and the PPT control signal is transmitted immediately and reliably. The radio range is general limited by the restricted transmitting power, the antenna sensitivity, and other environmental factors. The success deployment of this technology extends the coverage of a radio network without using expensive repeaters or links up multiple radio networks in the world.

ATAs(FXS) Gateways

VoIP ATA (Analog Terminal Adapter) is a telephone extension to the IP network.  It offers a traditional telephone line (PSTN) interface to an analog telephone, PBX line extension, or a fax machine.  Its WAN port interface allows access to the IP network in order to offer voice and fax services.  It is a great way for turning a traditional PBX to access the low cost VoIP services and for deploying VoIP service by an ISP.   An additional Ethernet port allows broadband connection for the existing PC or other network device without buying additional network equipment. 

VoIP FXO Gateways

FXS+FXO Gateways

A VoIP FXO (Foreign Exchange Office) Gateway bridges the VoIP and PSTN networks by enabling both voice and fax communications.It offers an FXO interface to a traditional telephone line (PSTN) and an WAN Ethernet port interface to the IP Network. A connection can be initiated either from a VoIP user to a PSTN user or from a PSTN user to a VoIP user. It is a key component for building a hybrid communication systems with connections to both VoIP and PSTN networks.The key advantage is to make use of the IP network and local PSTN networks to save on international / long-distance phone expenses.

PSTN Bypass Gateways

FXS with Bypass Gateways have the function to escape, and ordinary telephone line backup. This series gateways can meet need of H.323 and SIP systems for operators, and do not required to upgrade when convert SIP and H.323 protocol. The Gateways provide a standard 24V FXS phone interface complies with the ITU Telecommunications Standards, Can meet a variety of standard telephone and cordless phones. Regular telephone line backup port can be inbound and outbound, caller ID are forwarded directly to the phone. The gateway is set flexible, thin, light and full-featured, low temperature, and good sound quality

IP Telephones

The IP Telephones is a low cost desktop IP phone that is suitable for both business and residential users.  It offers all the common features required to interface with an IP PBX for most phone functions or call demand.   It offers lots of features and works seamlessly with most of the existing VoIP systems.  It is an ideal solution for both residential and business market to replace the traditional analog and digital (pbx) phones.
