I have a small Call-Center(10 agents) set up at the same location as the BCM 400. They work on digital sets. Everything works great. There are 16 IP sets off of the BCM at another site. Calls have no problem going between the 2 sites.At the remote site(IP sets) I am trying to set up 2 Agents. Set up ok. Can log in to queue ok. When a call is delivered to set, the intercom button rings but cannot answer it. It just keeps ringing and eventually forces the agent off. If I log the agent off, I can call the Intercom of the IP set from the Main site with no problem. Do I have a network problem? Any help is appreciated.
