The connection to the PBX system is established using SIP / TCP.
The connection is established either directly to a CS1000 node or to a Network Routing Service (NRS).
Connect to Communications Server
This is a direct connection to the CS1000 node. Input the IP address of the CS1000 server nodes here. The standard TCP Port for the SIP connection is 5060.
See also configuring CS1000 Node.
Connect to Network Routing Service
Input the IP address of the primary and optionally the secondary NRS here. The standard TCP Port for the SIP connection is 5060.
Connection over the NRS requires the configuration of the CS1000 node sip URI and the ECSTA gateways sip URI.
CS1000 Node sip URI
Input the sip URI of the CS1000 node, for the devices that are supposed to be used over this instance of the ECSTA. The sip URI Endpoint consists of the sip Gateway Endpoint Name from the CS1000 node configuration and the service domain.
See also configuring CS1000 Node.
The CS1000 node must be registered in the NRS configuration under gateway Endpoints.
Example: sip:SS_SIP@service_domain
See also configuring Network Routing Service.
Link to interface IP / TCP port
For SIP communication an IP port is required. This is automatically registered in the Windows® Firewall.
You can link the SIP communication to a specific IP interface. Please note that the IP interface used must be located on the same network segment as the CS1000 node or the NRS.
