<div dir="ltr">This is a core step of the CCIE Voice lab... all the PRIs are fractional and on a 6608, you need change B-channel maintenance state and on IOS, you configure as normal but leave off the ccm config and create the PRI group as you would if it were a fractional for H.323 (with service mgcp as stated below).<br>
<br>It is supported, by the way. As is the fractional on the 6608.<br><br>However, you also need to manually enter your MGCP commands (package-capability sst, rtcp, etc...) as these will not be downloaded from ccm.<br><br>

Not sure if 4.1 is different than 6.X, but in order to do a frac PRI you<br>
can't do the ccm-manager config. All you would do is create the PRI group<br>
with the service MGCP at the end. Then create a dial peer:<br>
<br>
Pri-group timeslot 1-12,24 service mgcp<br>
<br>
Dial-peer voice 1 pots<br>
Service MGCPAPP (or application MGCPAPP depending on IOS)<br>
Port 1/0:23<br>
<br>
I would THINK, that you should be able to do something like<br>
<br>
Dial-peer voice 2 pots<br>
Service MGCPAPP<br>
Port 1/1/0 (FXS Port)<br>
<br>
Not sure, haven't tried that on 4.x or 6.x.<br>

I have some sites where the MGCP controlled b-channel is busied out for<br>
fractional. Not supported but it works.<br>

May be able to hack it to work by busying out the unused channels from a<br>
callmanager perspective through the maintenance service parameter, but<br>
definitely a hack.<br>
