<div dir="ltr">Guys,<div><br></div><div>I have a question, it is a simples question, but i was trying to find some documentation about that, and i cannot find some real explanation.</div><div><br></div><div>Well my customer has 5 Collab Servers (3 CUCM and 2 CUCM IM & P), all of them virtualized above VmWare and UCS Machine, 2.5K IP Phones.</div>
<div><br></div><div>My question is, i have a SIP Trunk from CUCM and CUCM IM & IP and i am using the certificates from CUCM and CUCM IM & P to make this a Secure SIP Trunk, not non Secure.</div><div><br></div><div>
My CUCM and CUCM IM & P are using authentication with Microsoft Domain Controlles TLS on TCP/636 port using AD certificate imported on both clusters.</div><div><br></div><div>I have a key token this token is installed under both servers, making SIP and SCCP Secured. So everything here at my customer is not non-Secure.</div>
<div><br></div><div>My final question is now this machines need be moved from one vlan to another, and these IP adressess need to be changed.</div><div><br></div><div>I think that probably i will have lots of problems with that, so am i right, that i will need to generate again certificates and make all the authentication between this systems work properly after this modification?</div>
<div><br></div><div>Thanks a lot.<br clear="all"><div><div>--</div><div>Michel Perez</div><div>Skype: michelmbperez</div><div><a href="mailto:michelmbperez@gmail.com" target="_blank">michelmbperez@gmail.com</a></div><div>
