Callme button do not work in red5 0.1.08

Hi,

Installed successful under Linux Openfire                     3.6.2 and Red5 0.1.08. Played with red5phone user interface, all is working Ok - registering/dialing/etc. Next tried callme button - no effect, no log records - nothing. Anybody has working callme button in 0.1.08 version ? What to do to make it working ? What logs has to be viewed ? What debug variables have to be enabled ?

Thanks in advance.
