My workplace uses Cisco IP communicator as a softphone for employees.

I have found it to be quite unreliable for receiving incoming calls. When my wife calls me, she intermittently gets forwarded straight to my voice-mail (which implies that there is a disconnect between the client and server). Sometimes she will have to try and call 3-4 times before it starts ringing on my PC.

I suspect this is a flapping issue of some sort where the client is constantly being disconnected from the server for short periods of time, and if the incoming phone call comes at a time when it is connected properly, my phone will ring.

Today when I came into work, there was the following message on my screen:

Windows has detected an IP address conflict

It sounds like this could be connected. Any recommendations?

Talk to your IT staff - apparently the same ip address is being given to more than one system - this could indicate that someone has your IP address set statically or DHCP is having issues.

If its an issue, its with connectivity with your system as a whole, and is something your admin would need to look into - it WOULD explain the client not working, but there would be other signs - check ipconfig to see if you have a valid ip address and look at the network icon to see if you're connected. Have you had any other issues with your system's network related resources?

I have had some network flapping in the last few days (where my entire LAN connection would disconnect/reconnect) but this is the first time I have seen this error message. However, the soft phone has been unreliable for a very long time. – LeopardSkinPillBoxHat May 2 '11 at 2:29
the network 'flapping' indicates a misconfiguration somewhere - its a definite fixable issue, or at the very least indicates an issue with the network as a whole that needs fixing. as for the softphone issues, there's not enough information to tell what's wrong - i can't seem to find anything on where it'd log things - something your staff will know. – Journeyman Geek May 2 '11 at 2:34
