Using LRT how to Load balance Next-hop

Hi Team,

I want to use below LRT to send incoming call to three IVR servers as equal distribution between them.

when i tested it, i found all calls going to 1st IVR "10.172.19.76".

I changed the prio and weight to many values but i could get the calls going the other two IVRs

Do i miss anything in the below LRT ?

<?xml version="1.0" encoding="US-ASCII" standalone="yes"?><localRoutes>

<route format=”weighted”>
<user type=”E164”>8334672910</user>
<description>Toll Free</description>
<next prio=”0” weight=”35” type=”regex”>!^(.*)$!sip:8888889990@10.172.19.76!</next>
<next prio=”0” weight=”35” type=”regex”>!^(.*)$!sip:8888889990@10.172.25.76!</next>
<next prio=”0” weight=”30” type=”regex”>!^(.*)$!sip:8888889990@10.172.26.76!</next>
