After much deliberation, we have made it work using an H323 trunk, but only for calls arriving from an IOS ingress GW. We had to set Service Parameter <em><span style='font-family:"Arial","sans-serif"'>Send Multicast MOH in H.245 OLC Message </span></em>to <em><span style='font-family:"Arial","sans-serif"'>false</span></em> to allow it to work with CVP's H323 stack. We also discovered several bugs, one included calls from IP Phones, where the call flow was IP Phone -> CVP -> VXML GW -> Agent IP Phone resulted in a phone publishing audio to the MMOH group instead of subscribing. Thankfully we worked around this one as it could have been a serious privacy issue. Another was that the MMOH source interface on the IOS gateway had to be a physical (not a loopback interface).</span><o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal><span
