I am having some problem with my UC. My office is using CUCM6.0, a 1750 voicegateway with 2 ports FXO card and 6 7960 IP Phones.
The strange thing just happened recently. I noticed when there is an inbound call to the ip phone the phone will ring and hang therefore it will be non stop ringing until i pull out the cable to restart.
May I know what is the problem? Previously my office UC is working fine.
