color=#0000ff size=2>Looks like you've got the basics down. If the
connection between offices is data then just create an ICT pointing to the
servers in the other cluster (and do the same on their side) and use a route
pattern to route calls via the ICT. Make sure the IP routing
works to their servers and from their voice vlan to yours and you'll be good to
go. For QOS between them ICT calls are just like
H.323.</FONT></SPAN></DIV>

there any documents or can anyone comment on what is needed and how you go about
connecting multiple call manager clusters together. </FONT></SPAN></P>

size=2>1. </FONT></SPAN><SPAN
lang=en-us></SPAN><SPAN lang=en-us></SPAN><SPAN lang=en-us> <FONT face=Arial
size=2>We are going to need some type of</FONT></SPAN><SPAN
lang=en-us></SPAN><SPAN lang=en-us> <FONT face=Arial size=2>connection to
them. I assume this would be a T1 at minimum. If it is one cluster,
we should only need one to the main location. </FONT></SPAN><SPAN
lang=en-us></SPAN><SPAN lang=en-us> <FONT face=Arial size=2>If there are two
clusters we will need a connection to both.</FONT></SPAN><SPAN
lang=en-us></SPAN><SPAN lang=en-us><FONT face=Arial size=2> Our network is
using Sprints MPLS cloud. We should be able to drop connections from those
two</FONT></SPAN><SPAN lang=en-us></SPAN><SPAN lang=en-us><FONT face=Arial

lang=en-us></SPAN><SPAN lang=en-us> <FONT face=Arial size=2>Traffic between the
locations will use G729 to get the best use out of the smallest
connection.</FONT></SPAN><SPAN lang=en-us></SPAN><SPAN lang=en-us><FONT
face=Arial size=2> We do this between our existing two
locations.</FONT></SPAN><SPAN lang=en-us></SPAN><SPAN lang=en-us></SPAN></P>

lang=en-us></SPAN><SPAN lang=en-us> <FONT face=Arial size=2>If they are
using</FONT></SPAN><SPAN lang=en-us></SPAN><SPAN lang=en-us> <FONT face=Arial
size=2>extension ranges that conflict with our existing ranges, each office will
need to do some type of translation to avoid someone having to change extension
ranges.</FONT></SPAN><SPAN lang=en-us></SPAN><SPAN lang=en-us><FONT face=Arial
size=2> For example if they have an ext 2352 and we have an ext 2352, we
will need to assign a leading digit to each office. I might dial 6(2352)
to get to them and they would dial (7)2352 to get to</FONT></SPAN><SPAN

size=2>4. </FONT></SPAN><SPAN
lang=en-us></SPAN><SPAN lang=en-us> <FONT face=Arial size=2>Instead of routing
calls to those offices extensions out to the PSTN, I would route them across the
connection to the other offices and they would have routing set up to accept the
digits I sent, and convert them back to the proper extension for routing the
call to the correct location.</FONT></SPAN></P>
