SIP Profile - Proxy

Within the SIP network a SIP Proxy server manages the setup of calls between two SIP devices including the control of routing calls. The SIP Proxy server can also perform the necessary functions such as registration and authorization. Communication to the SIP Proxy server is configured on the IMG 2020 by configuring the server as an external gateway. The SIP Proxy object along with the External Gateway object are used to configure the various settings needed to communicate with an external SIP Proxy server. Refer to the information below.

To be able to modify the fields within the SIP proxy server object, the SIP Profile ID field within the SIP Profile - SGP object must have the ID  configured to something other than ID:0. First, create a SIP Profile with an ID other than 0. Once this is completed, the SIP Proxy object created under that SIP Profile (SGP) object and can be edited/modified.

When creating and configuring the SIP Proxy object, the SIP Proxy is considered an external gateway to the IMG 2020. Before an IP address or Hostname is displayed in the IP Address or Hostname field of the SIP Proxy object, the External Gateway object with either the IP address or Hostname must first be configured. Once this is completed, the External Gateway configured will appear in the Gateway field of the SIP Proxy object. Once the External Gateway is selected, the IP Address or Hostname of the gateway selected will be automatically populated in the IP Address or Hostname field below it.
