golgoj4 thanks for your quick response, I will follow your instructions, to re-install on a fresh 7.10 Hybrid, and I will update you with the results.
Yes, it was the password used from the gen_sip details in the broadvoice account page.
Here's some history FYI:
The only thing I think I did wrong the first time I installed on 7.10, I used the following parameters:
---------------------------------------
username= Portal username
password= auth_password
Phone number= phone_number
---------------------------------------
After that I went, and restarted the wizard and modified the setup to:
---------------------------------------
username= phone_number
password= auth_password
Phone number= phone_number
---------------------------------------
After that the Hybrid was answering the calls, I left a message and crashed the system, so rebooted and fixed manually the file system "fsck" because system couldn't auto repair it, than I went to the phone line setup in the Admin page I saw there is 2 entries, so I deleted the first phone line which has the wrong configuration, after rebooted the system, LMCE was not able to answer any calls!!!
