<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>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. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>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?<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>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.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>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?<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>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.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

of redundancy and simplicity, then it sounds like SCCP is the way to go.<o:p></o:p></span></font></p>

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.<o:p></o:p></span></font></p>

wanting to. Otherwise it’s a pretty nice box and is simple as all

the port density but we couldnt get around the dual interface requirement.
