Hi,<br><br>On a large install.. MTP for every call to the PSTN would not be very scalable.. well your Cisco AM would love you, as you'd be buying a bucket load of PVDM's :)<br><br>I'd dig into the MTP MOH thing on the gateway.. it sounds like a bug.<br>
Out of curiosity though.. when it does work.. did you need a HW MTP? or did it work with the CCM SW MTP?<br><br>Cheers,<br><br>Tim<br><br><br><div class="gmail_quote">On Tue, Nov 18, 2008 at 3:47 PM, Andre Beck <span dir="ltr"><<a href="mailto:cisco-voip@ibh.net">cisco-voip@ibh.net</a>></span> wrote:<br>

</div>I repeatedly stumbled over a certain situation where not having an MTP<br>
actually leads to a problem even with only Cisco C(U)CM and Cisco gateways<br>
involved. That is when<br>
<br>
* The CCM and Gateway are connected via H.323 (either as a simple gateway<br>
or by mediation of a gatekeeper) and<br>
* Multicast MoH is configured.<br>
<br>
In this situation, the PSTN side of a call will not hear MoH but just<br>
receive silence unless the H.323 gateway is supplied with an MTP on the<br>
CCM side.<br>
<br>
I've seen this with 4.1.x and 5.x so far. With 5.x I had stability issues<br>
with the MTP stuff and disabled both MMoH and MTPs to get rid of it. A year<br>
of patches later, maybe I should retry this.<br>
<br>
For more information, just scan back in this mailing list (archives), I<br>
think I posted more detailed versions of my MTP issues here.<br>
