Prior to CCM 4.0, the number of rings was configurable only at the cluster level through the Forward No Answer Timer Service Parameter. In CCM 4.0 and later, you can configure the number of rings cluster wide with this service parameter or at the DN level with the No Answer Ring Duration field. The default value for the No Answer Timer Service Parameter is 12 seconds. You can figure approximately 4 seconds for 1 ring. Please see the links below for configuration details.

What about if a phone doesn't have call forward configured, it rings forever? or there is a flag that we can setup in order to limit the number of rings in tah phone or line.

Thankyou.

Unfortunately, this usually has to be set at the line level or set up a device pool to group the phones that you want to adjust for the number of rings. The parameter is No Answer Ring Duration, under Call Froward and Pickup settings. You can also use the MLPP option with Precedence Alternate Party, but that tends to get a bit convoluted. I would stick with changing at the Line level, depending on the number of devices that need to be modified. I think there is a flag under the CallManager Service Parameters as well, but I will have to check out the settings on my lab at home to confirm.

I tried to finf the No Answer Ring Duration under Call Froward and Pickup settings with out success, i have callmanager 3.3(4) release, so i dont know if this paremeter exist under other option in this release.

Any help would be appreciated.

Thank You

Prior to CCM 4.0, the number of rings was configurable only at the cluster level through the Forward No Answer Timer Service Parameter. Take a look at the following link.

I already set the Forward No Answer Timer in the service parameters, but this works only when CFNA is present for the line. If no CFNA is configured the phone rings around 180 seconds or more.

Any ideas?
