Hi

when i use MeetMe, i have this errors:
    app_meetme.c: Unable to open pseudo device
Where is the problems ?


i have too warning and error into my logs:

[Nov  1 07:26:17] WARNING[18544] res_musiconhold.c: Unable to open 
pseudo channel for timing...  Sound may be choppy.
[Nov  1 07:26:17] WARNING[18544] config.c: Realtime mapping for 
'iaxpeers' found to engine 'mysql', but the engine is not available
[Nov  1 07:26:17] ERROR[18544] codec_dahdi.c: Failed to open

What is the process for resolv this problems ?

"Realtime mapping for 'iaxpeers' found to engine 'mysql', but the engine 
is not available", i don't understand because
realtime Sip+Extension works and cdr too

Thanks for your help
