<P class=MsoNormal style="MARGIN-BOTTOM: 12pt">A few options:<BR><BR>1. Upgrade
to CCM 6.Xor 7.X so you don't need the MTP anymore.<BR>2. Provision a separate
CallManager (or 2) for the sole purpose of acting as an MTP and increase the
number of possible channels on it.<BR>3. Purchase some CMMs<BR>4. Purchase some
3845s loaded with DSPs.<BR><BR>Options 2, 3, and 4 don't really make much sense.
As soon as you had CMMs, 3845s, or extra IPVMSApp CallManagers you wouldn't
really need your SIP conference solution anymore.<o:p></o:p></P>

<P>Since the SIP trunk requires an MTP, what could I use for MTP resources to
