SIP Stack G.711


Ocha's SIP stack with support for G.711 codec can process thousands of calls per second as it takes small amount of bandwidth to transmit the call data. The VoIP-based codec receives SIP requests from a client and then forwards the requests on behalf of the client. The SIP platform provides enhanced features such as multi-login facility, authentication, call answering, routing, auto-dialing, call retransmission, security and much more application level functionalities that simplifies and accelerates the VoIP-based application development to a substantial extent.
