[cisco-voip] Callmanager implementation over Internet

[Lelio Fulgenzi]

This worries me. We just had a talk with Cisco and they said as long as you open only the ports you require and use CSA and AV you should be Ok. We haven't opened things up to the Internet, but it will be a campus allowance. We want to begin using IPC and other hardphones that don't have CDP.

I can just see the hassle.

  You can use the SCCP proxy by Metreos to accomplish this and still remain secure.  

   

  I have implemented a callmanager/unity directly on the internet in the past for a company in your same situation.  Their server had more worms in viruses in 1 week than I've seen in my whole life (even with CSA & AV, they were able to take control of the server through a buffer overflow we think and disabled these services).  Perhaps CCM5 would be better suited for this purpose, or you could use your pix to only allow the necessary ports.

  Hi All,
  We have Call Manager and Unity hosted in Data Centre. All our clients have VPN connection to Data Centre. I am using PIX 515 at Data Centre and PIX501 at clients side. All are working perfect except voice quality issue some times. Since this is PBXL hosting service and security is not that much concern, I am wondering I can setup phones to acess CCM and Unity over the internet using gloabl IP address on Cisco IP Phones. Has anyone every implemented CallManager and Unity over internet? Your comment and advice would be greatly appreciated. 

  Best regards,
  Manoj
