I would suggest you upgrade and use IME which was created for this exact purpose...but that's obviously not the answer you were looking for. . .

Subject: [cisco-voip] Connecting to third party CUCM via ICT trunk


Hi,
I am looking for some advice. I have a CUCM 6.1 system at one of my sites and we have a third-party who is on our WAN (but controls their own LAN and servers etc) who also has a Call Manager (not sure what revision) and they would like to make calls between the two sites. I was thinking it would probably be fairly easy to setup an ICT trunk between the two systems but I am sure our security team would have some issues with that. Is there any way of making the trunk more secure? Locking down ports on the firewall etc, maybe some kind of VPN connection? Is there anyone out there that has done this that could share their experiences?
Many thanks,
Damian
