Ok, here is what I have found so far from my SE about the vg224/SCCP/redundant Link scenario...<br><br>This is undocumented on CCO at the moment (unless it's hidden real good)<br>If you bind SCCP to the L0 interface, you can use the MAC address for f0/0 in callmanager to set up the ports and it works fine. you can shut down f0/0 or unplug it and it will keep working from the f0/1 interface. I dont have any additional details yet but that sounds promising.. I'm trying to get an official nod that this setup would be TAC supported.

<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; color: navy; font-family: Arial;">For the Loopback
address, let me explain some of my statement. You can enter a Loopback
address. We use EIGRP at our site. VG224 does not support EIGRP,
it does seem to support RIP and OSPF. RIP could cost you a subnet to
have a loopback (not sure if v2 is supported). I didn't feel like
redistributing EIGRP into OSPF just for one device (if you have multiple
vg224s in one location that may make more sense for you). The other
option is to set multiple static routes on the VG224 and your default gateways
to get that loopback address into your routing tables.
</span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; color: navy; font-family: Arial;">My philosophy is:
These are phones, there is a much higher expectation of uptime and
low-latency. Do I want to support fancy and complicated or do I want to
support stable and simple?</span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; color: navy; font-family: Arial;"> </span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; color: navy; font-family: Arial;">As for the
SCCP/MGCP:</span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; color: navy; font-family: Arial;"> </span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; color: navy; font-family: Arial;">That is correct, SCCP
does provide more features than MGCP. However, if you're trying to use
the redundancy of two Ethernet interfaces you can't in SCCP because it wants a
MAC address, you can only enter one address in
CCM.</span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; color: navy; font-family: Arial;"> </span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; color: navy; font-family: Arial;">If you're attaching
analog devices, what particular features that SCCP provides did you
want? Would you be doing blind transfers with a fax machine or credit
card machine? If analog phones, will the phones even support the
features you want to use?</span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; color: navy; font-family: Arial;"> </span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; color: navy; font-family: Arial;">In SCCP world, the
configuration is split between the VG224 and the CCM. You have to
configure the CCM and in the VG224 configure each analog port as well.
In MGCP you enter 3-5 basic commands in the VG224 to point it to your CCM and
from there all the configurations for the ports are done on the CCM. If
you're familiar with the IOS commands, that may be a non-issue, but if
anything doesn't work, or you need to make changes, you now have essentially
two separate configurations to administer for every
line.</span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; color: navy; font-family: Arial;"> </span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; color: navy; font-family: Arial;">So if the features in
SCCP override the advantages of redundancy and simplicity, then it sounds like
SCCP is the way to go.</span></font></p>

<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; color: navy; font-family: Arial;">I use a
VG224. I have currently not been able to find a way to make the two
Ethernet Interfaces work as redundant interfaces as far as CCM is
concerned. If you're using SCCP to CCM you have to specify the MAC
address so that doesn't work. If you're using MGCP, you enter the IP
address of the device. Using a loopback address will not work.
It looks like you might be able to use HSRP, but I've never tried
it.</span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; color: navy; font-family: Arial;"> </span></font></p>
<p><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; color: navy; font-family: Arial;">Someone here can
speak to the redundant interface issue I'm sure, but just know that even
though it says it's running IOS, it's not as robust. Just because it
has two Ethernet interfaces, it doesn't mean you can use them the way you
may be wanting to. Otherwise it's a pretty nice box and is simple as
all getout to configure in MGCP.</span></font></p>

vg224's on order for a project this summer, the reason we chose them
instead of the 248's was we had a requirement that the devices all needed
dual ethernet interfaces (is for a dorm on remote campus). 248's would
have been less expensive due to the port density but we couldnt get around
the dual interface requirement. Haven't recieved them yet so I can't
comment on anything else about the 224's. <br><br>We've been using the
248's in our health sciences center, haven't really had any problems with
them. I'd prefer IOS on them but thats my only real complaint. No one has
tried to hook up a high speed fax yet though, I heard those werent
supported unless you turn them down. </span></font></p>

requires 128 ports (perhaps more) and we only have experience (mostly
good) with the vg248. I'd rather keep our inventory similar so I'm leaning
