In your dialplan, you'll need to set the _ALERT_INFO variable to whatever
you'd like your ring to be.  Your choices are in sip.cfg in two places:

Right at the beginning, you'll see a line like this:

<alertInfo voIpProt.SIP.alertInfo.1.value=""
voIpProt.SIP.alertInfo.1.class=""/>


And then later on, you'll see some lines that look something like this:

      <ringType se.rt.enabled="1" se.rt.modification.enabled="1">
         <DEFAULT se.rt.1.name="Default" se.rt.1.type="ring" ... />
         <VISUAL_ONLY se.rt.2.name="Visual" se.rt.2.type="visual"/>
         <AUTO_ANSWER se.rt.3.name="Auto Answer" se.rt.3.type="answer"/>
         <RING_ANSWER se.rt.4.name="Ring Answer" se.rt.4.type="ring-answer"
se.rt.4.timeout="500" se.rt.4.ringer="7" />
         <CUSTOM_1 se.rt.8.name="Custom 1" se.rt.8.type="ring"
se.rt.8.ringer="5" se.rt.8.callWait="7" se.rt.8.mod="1"/>

In the alertInfo at the beginning, put in one of the name fields like
"Custom 1", and then for the class enter the corresponding number specified.
For example:

<alertInfo voIpProt.SIP.alertInfo.1.value="Custom 1"
voIpProt.SIP.alertInfo.1.class="8"/>

Then in your dialplan, set _ALERT_INFO to Custom 1:

Set(_ALERT_INFO=Custom 1)                ; Notice there are no quotes


You can set multiple distinctive rings by increasing the number on the XML
tag:

<alertInfo voIpProt.SIP.alertInfo.2.value="Custom 2"
voIpProt.SIP.alertInfo.2.class="9"/>
