Allow Skype-Group Messages To Be Sent Via Minecraft Server Commands?

I'm an admin on a Minecraft server, for about 2-5 hours a day staff are not able to be on the server, the server is hosted from a hosting company, i have seen plugins that allow players to send messages in a group, start calls, etc from Skype, but the servers have to be hosted on a PC, so Skype can be linked, is there a plugin that we can put in, that allows for people to send messages to the group through Minecraft?
