Communication communigate pro3/22/2023 ![]() ![]() If the callee accepts the request, the callee UA sends the response back to the server,Īnd the server relays it back to the caller UA. Retrieves the active registration for that user and relays the request to the callee UA. If the SIP identificator belongs to a local user, the SIP server The SIP serverĬhecks the identificator, and if it is served by a remote SIP server, relays (proxies) the Sends a request to the SIP server with the SIP identificator of the callee. When a SIP session is being initiated, a caller SIP client program (or UA - user agent program) Of other Domains on the same server, or with SIP users served by other, remote SIP servers. SIP users within the same CommuniGate Pro Domain, with users The SIP Module allows users to initiate sessions (phone calls, chats, etc.) with other As a result, all CommuniGate Pro Aliases, Forwarders,Īnd Router records are available for SIP communications, too. The SIP Module uses the CommuniGate Pro Router mechanism SIP identificators have the same form as E-mail addresses: the CommuniGate Pro system, the user SIP identificator is the name of the userĪccount, so the user SIP identificator name is the same as the user E-mail address. SIP users to communicate with each other without the knowledge of the networkĪddresses being used, using just the "SIP identificators". User may have several registrations active if that user has severalĬommunication devices in the on-line mode (the office IP Phone, the desktopĬomputer, the instant messaging program on a laptop). Registers the users by remembering the network (IP) addresses they use. SIP devices (IP phones, AV conferencing tools, Instant Messaging tools) toĬonnect to the CommuniGate Pro SIP module when they go on-line. The SIP module implements Registrar services. (TLS) communications over the TCP protocol. The CommuniGate Pro SIP module supports UDP and TCP communications, and it also supports secure if no Server transaction can be found for an ACK request, a SIP Client transaction is created to relay the.Module itself, without using the subcomponents. if no Client transaction can be found for a response packet, the packet is relayed "upstream" by the SIP.While SIP response packets are submitted to the SIP Client subcomponent, with two exceptions: SIP requests packet received with the SIP Module are submitted to the SIP Server subcomponent, This transaction is used to send a SIP request via some Internet protocol, The module uses the SIP Client subcomponent to create a SIP Client transaction. The Signal module can relay a request to a different SIP device or SIP server. Them back to the source of the SIP request. The responses generated with the Signal module are submitted to the SIP Server transaction, and the SIP Server sends In other cases, the SIP Server component uses the Signal Module to process the request. This happens with protocol-only requests or requests that cannot be processed. The SIP Server component may process the request itself and send a response back. Request packets are submitted to the SIP Server subcomponent, to a new SIP Server The SIP module parses all received SIP packets, and uses the module subcomponents to It also sends the response and request packets via the TCP and UDP network protocols. The module uses TCP and UDP listeners to receive SIP request and response packets via these network protocols. The CommuniGate Pro SIP Module implements the SIP protocol functionality. Manage those sessions (add new parties, close sessions, update session parameters, etc.). On the network, to negotiate the media transfer protocol(s) and protocol parameters,Įstablish the interactive real-time sessions, and to Instead, it allows all participating parties to find each other The SIP protocol does not include the protocols required for actual data Implements the SIP Internet protocols via The CommuniGate Pro SIP module provides the infrastructure for real-timeĬommunications, such as instant messaging, audio (IP telephony) and videoĬommunications and conferencing, shared whiteboards, and others. ![]()
