Problem conf softkey sccp driver


I’ve installed a chan sccp-b driver with conference option.

In my Cisco 7940 phone, the softkey display is “conf.”, but the softkey is disabled.

In my sccp.conf, i have rename confrn to conf because confrn display “undef” in my phone.

thanks for your answer to activate the conference softkey.

ps: il use asterisk with chan sccp-b 3.0 RC3.1
