As is true with most organizations today, we are under pressure to reduce costs where we can. Some users are coming and asking why we are not using Skype for international calling. I'm not sure if I fully understand the risks so I am posting this question here on ITKE.
Has anyone implemented Skype for their organization and is supporting it on company networks and equipment? If not, why not? If you have implemented Skype services, some additional information would be useful.
What precautions were required before implementing this service/application?
What has network usage been like since implementation?
What configuration changes at the firewall (both edge & client) were needed to support the application?
Please feel free to share any other advice you may have about this type of service/application.
