We have a hospital site that has multiple buildings close to each other. Nurses roam from one building to the other via IP Mobility. 99% of the time everything works fine, but we have been having intermittent issues with some phones.
We are using the Cisco 7925 phone. Sometimes when a users roams from one building to the other, the phone will get stuck and will not roam properly. The phone will say "Configuring CM List" and will just continue to loop in that matter. Below are some of the things we have found when this issue happens:
* In the originating controller, the phone is listed as Away.
* In the current controller, the phone is listed as Visitior.
* Phone cannot be pinged from either controller.
* If phone is taken back to the originating building, it will come up fine and register.
* If phone, while back at original location, a call is placed and roam back to the problem location while on the call and ended at the location, phone will stay at the Visitor location fine.
I have not been able to replicate the issue and it only happens to some phones at the most once a day. Has anyone encounter this issue? Anyone have any idea what could be causing the issue?
