<p class=MsoNormal>Hi all,<o:p></o:p></p>
<div>
<div>
<div>

<p class=MsoNormal style='margin-bottom:12.0pt'>First let me lay out the
situation, we have a mixture of offices with a mixture of phone systems
including meridian, siemens DX, siemens Hi-Path and Cisco Call Manager. They
are all part of a local Featurenet system where they can make (5-digit)
extension to extension calls to each over what amounts to a private phone VPN
(mainly DPNSS over E1)<br>
We have a trusted third party whom we have a firewalled off 2mb data link to
who has a call manager 4.x.<br>
The idea is for us to be able to make calls and receive calls to this call
manager 4.x<br>
Would it be possible to setup an Intercluster trunk between their call manager
and one of ours (we have a 4.1 and a 6.1) and have them break out onto our
private phone VPN from our call manager?<br>
To hopefully make it more clear<br>
<br>
Site A - trusted third party with call manager 4.x (extension range 68xx)<br>
Site B - internal site with call manager (extension range 66xxx)<br>
Site C - other internal site with another phone system (extension range 20xxx)<br>
<br>
So if we setup an Intercluster trunk between Site A and Site B would Site A be
able to call Site C and vice versa?<br>
Also would anyone know what ports we would need to open on our firewall (we
would have to NAT the connection) to allow this to work.<br>
Thanks,<br>
