I’m trying to create a conference service for my Asterisk-based IP-PBX using Meetme application. The meetme.conf file has this: [rooms] conf=\>2 The extensions.conf file has this: exten =\> 200,1,MeetMe(2,DpM,1234) The problem is that when I dial “200” always get a message of invalid conference number. Any ideas please. ---

why dnt u try conf =\> 2, 1234 then exten =\> 200,1,MeetMe(2,DpM,1234) * * * U have specified password in the exten but none exists for the hall. May be this could be the reason ---

Meetme needs a zaptel card or the ztdummy module for timings, did you have a zaptel card installed or the ztdummy kernel module loaded ? Cheers. Marco Bruni ---

Hi, I got the same problem, getting "app\_meetme.c:769 build\_conf: Unable to open pseudo device" And a message on the phone “that is not a valid conference number” (while it is ofc valid, according to the configuration). So i found this thread. Of course my ztdummy module wasn’t loaded, so i loaded it manually and restarted asterisk. Then lsmod to see if the ztmodules are there - they are. Retried calling the conf room number - but the logs and the error message are still the same. What else are we missing? ---

Ok, my solution was: chown -R asterisk:asterisk /dev/zap (gentoo x86\_64)
