SIP server on LM

[buuuudzik]

Hello,

I've tried to configure the SIP gateway on LM according to this manual:
http://openrb.com/sip-server-on-logicmachine/

and unfortunately I can't register my Linphone app to the LM.

My configuration is:
LM - 192.168.0.10
iPhone - 192.168.0.102
PC - 192.168.0.100

How can I check if the sip-package is installed properly?
