This feature enables users to have a custom ring tone set for their telephone. Custom ring tones can be set in following manner:

• Using the Call Filters & Blocking option under Enhanced Services when editing extensions
• Using the Custom Ringtone option when setting a DID
• Setting the desired ring tone for all phones in Settings->Servers, Edit

Call Filters & Blocking

If you want to set a custom ring tone (which can be done per extension), click on Enhanced Services when editing your extension. Enable the Call Filters & Blocking feature.
You can set a custom ring tone for anonymous callers or for known numbers. Just click on Destination Type and choose Ring Tone. In the Destination field, enter what ring tone you want and that depends on the phone that you have.

AASTRA phones

For AASTRA phones enter <Bellcore-drX> in the Destination field, where X is the number of ringtones, usually 1-5.

CISCO phones

For CISCO phones enter <Bellcore-drX> in the Destination field, where X is the number of ringtones.

LINKSYS phones

Enter the name of the ringtone, Simple-5 or Classic-2, for example. Ring Tone names can be checked on LINKSYS phones Settings->Ring Tone menu.

POLYCOM phones

To set a custom ringtone on a POLYCOM telephone, you need to edit the sip.cfg and ipmid.cfg files. In sip.cfg, look for the line with these variables:

<alertInfo voIpProt.SIP.alertinfo.1.value="Sales" voIpProt.SIP.alertInfo.1.class="8"...>

With 'class' you choose which ring class you want to use when you set 'value' as SIP header.
In this case, sending a SIP header with the value 'Sales' will cause the telephone to use the ringtone that is set in class 8 in ipmid.cfg file. In ipmid.cfg, class 8 line looks like this:

<SALES se.rt.8.name="Sales" se.rt.8.type="ring" se.rt.8.ringer="3" se.rt.8.callWait="6" se.rt.8.mod="0">

In this case, the telephone will use ringtone number 3. Signs like empty spaces or the " sign can be used in ring tone names if they are used with a backslash in front (ie. ").

Most phones don't support custom ring tones.

Custom Ringtone in DIDs

It is possible to set custom ringtones for extensions set as a Destination in DIDs if the phone on that extension is AASTRA, CISCO or LINKSYS. To set a custom ringtone for all calls coming from this DID, use the Custom Ringtone field, where you will enter the same as above, depending on the phone type.

Now every call that comes from this DID will have the same custom ringtone, whereas using Call Filters & Blocking you need to set the custom ringtone per extension and anonymous callers.
Also, if you use both ways for defining custom ring tones, the DID option overrides the Call Filters & Blocking ring tone.

Setting Custom Ringtone for all phones

To set a ringtone for all phones on the system, click on System->Servers then Edit. There you will find Ringtone for Local calls option under Features. Here you have the option to enter the desired ringtone for all the phones (info same as above).

NOTE: All phones which will use this must be the same.
