<div dir="ltr"><div>Hi Folks, </div><div>In the past, most sites will have a PSTN voice gateway. MMOH will be used for the users co-locating with a PSTN voice gateway. </div><div><br></div><div>Now, more and more providers in Europe/US/Canada are providing SIP trunk now. </div><div>As we know, certain music will tend to be distorted when we used G.729. </div><div><br></div><div>When we move over to SIP trunk, what's the best design for MOH for various scenario?<br></div><div><br></div><div>Scenario 1</div><div>Local voice gateway is available (acting as SBC). Preferably, MMOH will be playback for local user and PSTN users. </div><div><br></div><div>Is there any special CUBE configuration to convert MMOH playback locally to unicast MOH traffic before sending to SIP provider? Or I can only unicast MOH from CUCM and send it towards the SIP provider? </div><div><br></div><div>Scenario 2</div><div>Site without voice gateway. The service provider SBC can directly integrate with CUCM via SIP trunk. SBC (1 leg - connected to PSTN service provider network, 1 leg - connected to customer LAN) and CUCM sits in different site. In this case, how can I provide MOH to the SIP trunk provider? Unicast via G.711? </div><div>Is there better option out there? I feels that in this case, it's wasting of bandwidth when all my regular on-net calls are using G.729 only. <br clear="all"><br>-- <br></div><div class="gmail_signature"><div dir="ltr"><div>Regards,</div><div>Ki Wi</div></div></div>
