On an Experience Portal system that has both H.323 and SIP configured, when a CCXML application makes a <createcall> request, the MPP looks for an available H.323 port to place the call on before looking for an available SIP port. Experience Portal provides the ability for CCXML applications to request the MPP to look for an available SIP port first. The application can send the suggest_sip hint on the <createcall> request.

An example of the CCXML code that demonstrates how to make an outcall using SIP:

<var name="suggest_sip" expr="true"/>
<script>var hints= new Object(); hints.suggest_sip = suggest_sip; </script>
<createcall dest="'14085551234'" hints="hints"/>
