Hi Guys, 

 

My Customer have a solution with CUCM 9.1(2)SU2. He is configuring Extension Mobility for any models IP Phone, but, only 7821 model didn´t worked. The firmware version is sip78xx.10-1-1SR1-4. I found the bug CSCuj90768, but, not is clear for me if this is the root cause. 

The message error is that appear when the user try login is: session start without sucess

 

Any have idea about this?

 

Thanks a lot,


Wilson

Hi @wilsonsant,A few

Hi @wilsonsant,

A few questions:

  • Is EM functioning in other IP Phones inside the CUCM environment?
  • Under Settings > Phone Info > Active Load ... Is the phone loading the correct firmware version (sip78xx.10-1-1SR1-4)?
  • Is there a "Default Device Profile" for that phone model?
  • Is there a "Device Profile"? Is that Device Profile suscribed to the EM service?

Hope to see your answers.
