| Field | Description |
|---|
| Choose a name | Enter a unique name to identify this installation; if you are installing more than one instance of Echo on your network, the name you enter here will be used in the subsequent setup of your TIM Plus or TIM Enterprise server. |
| Network adapter | Choose the adapter that will receive SIP/SCCP and media packets from your network. |
| Buffer size | The socket buffer value is the maximum size (in bytes) that you'd expect your network adapter to receive from your network. The default value of 65536 should be sufficient for most networks. |
| Protocols | The types of IP packets that you know Echo should look for when inspecting passing traffic on your network adapter. If you know for sure that your audio signal or media packets will never be TCP packets, you should deselect TCP to save CPU load; the less traffic that Echo needs to inspect, the more concurrent calls it can handle with the same hardware. |
| SIP port(s) | The UDP/TCP port number(s) that will be used for SIP signalling traffic on your network. Usually this is a single port (5060) but, in the case of media proxies or multiple SIP registrars on the same network segment, further ports may need to be entered here. |
| SCCP port | The TCP/UDP port that you expect Cisco SCCP (Skinny) packets to be transmitted on. This value is normally port 2000. |
| End session if no audio | This value specifies (in seconds) the maximum amount of time that Echo will continue monitoring a SIP or SCCP session in the event of no traffic, before it considers the session abandoned. |
