A network location is a specific set of network settings that the contact center applies to endpoints based on the endpoint IP address. To map an endpoint to a specific network location, you must specify the endpoint IP address in the network location configuration.

If an endpoint does not have an assigned agent profile, the contact center uses the endpoint IP address to map the endpoint to the corresponding network location and the associated agent profile. If an endpoint IP address does not match any IP address in the configured network locations, the contact center uses the default network location.

On the Network Locations screen, you can configure network settings for endpoints on the same IP network, including the network name, agent profile, and IP addresses. When setting up network locations, you can configure VLAN settings and service quality parameters, such as call control, audio, and video PHB.

The contact center supports Real-time Transport Protocol (RTP) and Real-time Transport Control Protocol (RTCP) for transmitting media. With RTP and RTCP, the contact center can monitor transmission statistics and quality of service between enterprise SIP servers, endpoints, and external phones on PSTN. On the Network Locations screen, you can configure RTCP messaging parameters and quality monitoring server IP address and port number. If you require secure connections, you can configure Secure RTP (SRTP) and Secure RTCP (SRTCP) transmission settings.

You can configure the audio codecs to use for the calls and also determine the priority list for the codecs. The voice quality on a call depends on the network bandwidth that the audio codecs use. Currently, the solution supports G.711, G.729, and G.729b codecs to handle voice signals on contact center calls. G.729b is a superset of G.729 that activates silence suppression to save network bandwidth when no voice activity is detected on a call.
