Usage Guidelines | Use the ring number command to set the maximum number of rings to be detected before answering a |
| call over an FXO voice port. Use the no form of this command to reset the default value, which is one |
| ring. |
| Normally, this command should be set to the default so that incoming calls are answered quickly. If you |
| have other equipment available on the line to answer incoming calls, you might want to set the value |
| higher to give the equipment sufficient time to respond. In that case, the FXO interface would answer if |
| the equipment online did not answer the incoming call in the configured number of rings. |
| This command is not applicable to Foreign Exchange Station (FXS) or E&M interfaces because they do |
| not receive ringing on incoming calls. |
|
|
Examples | The following example on the Cisco 3600 series sets five rings as the maximum number of rings to be |
| detected before closing a connection over this voice port: |
| |
| ring number 5 |
| The following example on the Cisco MC3810 multiservice concentrator sets five rings as the maximum |
| number of rings to be detected before closing a connection over this voice port: |
| |
| ring number 5 |
