The MGCP loads can be used to interop with the EGW/PGW/BTS.<br>
<br>
In a callmanager you're stuck with SCCP or SIP<br>
<br>
SCCP still has the most features.<br>
some call control functions are not possible on SIP loads.<br>

the only way to run a SIP image
on your phone is to use CM 5.0 or a third party like Asterisks. MGCP
is
basically used form a VG to the CM. I don’t know if you can MGCP to a
phone. the nice thing about SIP is that it is basically standards
based.<o:p></o:p></span></font></p>

SCCP vs SIP

</span></font><font face="sans-serif" size="2"><span
style="font-size: 10pt; font-family: sans-serif;">We have a small ip
phone shop and all our phones run
SCCPxx.x. I've been asked why we don't change the firmware on our
phones
to SIP. I've been doing some reading on this but theres a few simple
things I don't understand. To switch an IP phone from SCCP to SIP or
MGCP, can I just apply that firmware or are there other considerations
or
pre-reqs? Do I need to purchase a different phone that will only run
SIP
firmware? Is there a comparison sheet out there that shows the pro's
and
con's for each of these types? I'd love to run SIP firmware only for
the
ease of reading sniffer traces. </span></font> <br>
