You can do DO-EO conversion, but it requires SIP-SIP and won't work on<br>
H.323-SIP.<br>
<br>
For G.729:<br>
You have to use a software mtp to do G729. CUCM doesn't support G.729<br>
in software MTP's, and the PVDM's won't do G.729-G.729, so it only<br>
leaves you with router software MTPs. If you haven't configured your<br>
MTP in the MRGL for your H.323 gateway with a SW MTP with G.729<br>
configured it won't work properly.<br>
<br>
For G.711:<br>
I would configure 'codec g711ulaw' on all dial peers, and drop the<br>
voice-class codec.<br>
<br>
If you can switch the H.323 gateway to a SIP trunk trunk, configured<br>
DO-EO conversion:<br>
<br>
voice service voip<br>
sip<br>
