[Asterisk-Users] SIP module load error

[Σταμάτης Κεκές]

Hello everybody.

I have a test box with asterisk and till now I have successfuly made it 
work with iax.
I'm trying to load the SIP module in order to test SIP with msn 
messenger but without any success.
In my modules conf when I have :

chan_sip.so=yes

The asterisk service starts but it does not load any SIP module. When I 
remove that line and I place a line after the chan_modem.so which is the 
following :

load chan_sip.so

then I recieve the following lines in my /var/log/asterisk/messages :

Mar 28 10:00:57 WARNING[1024]: File loader.c, Line 212 
(ast_load_resource): /usr/lib/asterisk/modules/chan_sip.so: undefined 
symbol: ast_moh_stop
Mar 28 10:00:57 WARNING[1024]: File loader.c, Line 319 (load_modules): 
Loading module chan_sip.so failed!

What happens with that ?
Is there any solution for that ?
