[cisco-voip] Callmanager implementation over Internet

[Lelio Fulgenzi]

When I asked the Metreos rep (I think he was an exec) it sounded very promising that they would continue the proxy line of appliances. Quite honestly, I think that's why they bought them. I hope the Metreos guys had a clause in there that said for every product they don't continue we can keep a small company on the side to make them. ;)

  Matt,

   

  Since the Cisco acquisition of Metreos, is this product even available anymore?  I hear people talk about it here and there on other lists but when I contacted my Cisco rep all I was told was that things are still in "flux" at this time and there were no product details.  I really wanted to look at the phone proxy since we are currently using Cisco 871/877's and VPN to do all of our voice.  Metreos would give us the option to use Citrix or TS and still utilize 7960 physical phones without being tethered to a $500 Cisco router.  Not that the 870 series routers are bad, but there are several situations where it would have been nice to not have to deal with them.

  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
