<div><br>
</div>
<div>I am working on trying to migrate some legacy ROLM PRI
connections from Cisco 3825 to Cisco ISR 4331. I am trying to
figure out the correct configuration on the ISR. The current
configuration on the 3825 looks like this:</div>
<div>
<div><br>
</div>
<div>Config 3825:</div>
<div>-----------------------</div>
<div>voice-card 1</div>
<div>!</div>
<div>controller T1 1/0</div>
<div> clock source internal</div>
<div> pri-group timeslots 1-24 service mgcp</div>
<div>!</div>
<div>interface Serial1/0:23</div>
<div> no ip address</div>
<div> encapsulation hdlc</div>
<div> no logging event link-status</div>
<div> isdn switch-type primary-dms100</div>
<div> isdn protocol-emulate network</div>
<div> isdn incoming-voice voice</div>
<div> isdn bind-l3 ccm-manager</div>
<div> no cdp enable</div>
<div>!</div>
<div>-----------------------</div>
<div><br>

<div>This is what I have on the ISR 4331 and some of the PRIs
ran clean and others had frame slips on the ROLM side.</div>

<div>Config 4331:</div>
<div>-----------------------</div>
<div>voice-card 0/1</div>
<div> no watchdog</div>

<div>controller T1 0/1/0</div>
