<b>Subject:</b> [cisco-voip] MoH on CME & Internal Network</span></p>
</div>
</div><div><div></div><div>
<p> </p>
<p>I’m running CME 7.0 and have a question on MoH.</p>
<p> </p>
<p>I’ve successfully changed my music-on-hold for my VoIP
system. However, my manager has told me he wants to play the
music-on-hold file for internal calls as well. Previously, the phone
would just beep to remind you that you have a call on hold (for internal
calls). For outside calls, the MoH plays fine.</p>
<p> </p>
<p>I’ve read that in order to play MoH for the internal
network, you have to do it through multicast. So on my router, I did the
following:</p>
<p>----------------------</p>
<p>ip multicast-routing</p>
<p>!</p>
<p>Interface GigabitEthernet0/0</p>
<p>ip pim dense-mode (also did sparse-dense-mode)</p>
<p>!</p>
<p>ccm-manager music-on-hold</p>
<p>!</p>
<p>telephony-sevice</p>
<p>moh On-Hold-Rev2.wav</p>
<p>multicast moh 239.1.1.1 port 2000 (I’ve also tried 239.1.1.3,
5, etc)</p>
<p>----------------------</p>
<p> </p>
<p>Things to note: All entries in ephone-dn have
“multicast-moh” enabled.</p>
<p> </p>
<p>What am I missing here? When I make the above changes,
our phones quit “beeping” when internal calls are placed on
hold. When I remove the ‘multicast moh 239.1.1.1 port 2000’
line, our phones beep again internally when on hold.</p>
<p> </p>
<p>Any help would be appreciated.</p>
<p> </p>
