Hello People / CUCME Experts, This is my very first post to this list, so hello to everyone, and i really hope to see if someone can suggest/recommend any troubleshooting action plan in which several Cisco 7961 loaded with the latest SCCP Firmware version (8.3(4) SR1) are displaying the Logging screen indefinitely and stays there forever, when configured to work with Extension Mobility, the same thing happens when trying to log out, the phone displays logging out indefinitely. We have to exit out of the screen on the 7961 phone to get back to the main screen. This is a basic configuration that I have running on my device (IOS Version 15.0(1)XA and Call Manager Express 8.0) voice logout-profile 1 user tphone-phone password 1234 number 201 type normal voice user-profile 2 pin 9999 user me password pass123 number 5 type cw-overlay speed-dial 1 135 label Scott blf ephone-dn 5 dual-line number 301 no-reg primary label 301 description PhoneA Analog name PhoneA Analog call-forward busy 341 call-forward noan 341 timeout 10 ephone-dn 10 dual-line number 201 no-reg primary label 201 description Phone Test name Phone Test call-forward busy 341 call-forward noan 341 timeout 10 ephone 5 device-security-mode none mac-address ABCD.ABCD,ABCD type 7961 logout-profile 1 telephony-service url authentication http://10.1.10.1/voiceview/authentication/authenticate.do Is there any way to troubleshoot/debug what could be going on ??
