fractional PRIs when running MGCP is not very well rounded.

<DIV dir=ltr align=left><SPAN class=148064417-03112006><FONT face=Tahoma
size=2>Used to be the only way you could really get this accomplished at all was
to use the "Change B-Channel Maintenance Status" service parameters to "busy
out" individual B-channels you didn't want to use, but this didn't scale well
when you had many fractional PRIs.</FONT></SPAN></DIV>

<DIV dir=ltr align=left><SPAN class=148064417-03112006><FONT face=Tahoma
size=2>Now it seems you are able to configure fractional service with an MGCP
configuration on the gateway, but the CallManager configuration context does not
yet consider fractional configurations. So if you use "ccm-manager config"
CallManager will overwrite these port's configurations exactly as you have
already seen.</FONT></SPAN></DIV>

<DIV dir=ltr align=left><SPAN class=148064417-03112006><FONT face=Tahoma
size=2>I frankly am not a big fan of "ccm-manager config" anyhow as there are
not enough people who understand that when they are tweaking knobs in CM they
are actually changing their router configurations... and performing the
equivalent of a "write mem" on those same gateways. I don't use it ever,
even when I'm turning a gateway up. </FONT></SPAN></DIV>

drawback.</FONT></SPAN></DIV>
