More issues with CallManager 6.0

I recently rolled out CallManager 6.0 for a customer and rather disappointingly we ended up having to apply an Engineering Special patch to fix the problems. Rather alarmingly, we found these bugs in version

  • Attendant Console is unable to allow you to select a Device Profile (Unable to change MAC address) however Attendant Console works fine when you choose to use a phone that is statically configured rather than using Extension Mobility.
  • Adding a new Device Profile to CallManager causes ccm.exe (or the Linux equivalant at least) to hang. Symptoms include CFWD state unchangeable, and attempting to log in/out of Extension Mobility causes the phone to endlessly say 'registering'.
  • Device profile Service URL is being overwritten by the actual devices' SURL. The symptom presents itself as the service URL that was being shown on the phone when the phone is EM logged out can still be seen when the phone has been logged into EM.

What's disappointing is that all three of these bugs were fixed in previous versions of CallManager 6, and somehow Cisco has allowed these bugs to get through to a later version. Does it have something to say about their Quality Control procedures???

Anyway. These bugs are all fixed in ES UCOS_ES_6.0.1.3103-1 or CallManager 6.1. Speak to Cisco TAC for further assistance.
