CoIP-32 CDMA Gateway

Our CoIPs ONLY support China Telecom network.In addition, we’ve developed our proprietary Remote SIM technology for SIM card management without inserting SIM cards to CoIPs. Together with the SMS Server and SIM Sever, you can now build your own system for voice traffics between VoIP and CDMA or a SMS Messaging system based on your application requirements. In addition, each CoIP is equipped with a Remote Control client which enables a secure remote access method for technical support and CoIP management. All of the above features are available at no additional charges.

Application
The concept diagram below shows a simple VoIP network for call center application.  It consists of a softswitch/IP PBX and VoIP clients such as an IP phone, a call center operator, and CoIPs.  All VoIP clients are configured to register to the softswitch/IP PBX.  For the CoIPs, each CDMA channel is inserted with a valid SIM card in order to access the CDMA network.  Both incoming and outgoing calls between the VoIP and CDMA/PSTN networks can now be realized.
