[asterisk-users] Asterisk 1.4 with Digium B410P - Timing problem

[Administrator TOOTAI]

Hi list,

we have a dual Xeon server with 2GB RAM running Debian Etch 2.6.18.4-686 
kernel. The server has 2 B410P cards plugged in. No other card.

We installed Asterisk 1.4 trunk with zaptel trunk, ran make b410p, the 
install mISDN1.1.0 (for bug 9064) configure and compile Asterisk with 
chan_misdn, all is fine. In misdn-init.conf we have added 
option=1,master_clock. Asterisk is up and running, voicemail, echo test, 
demo, MOH, everything works well.

Now we want to add conferences with meetme. So we load zaptel module who 
created /dev/zap/channel|ctl|pseudo|timer|transcode. Asterisk is running 
under asterisk:asterisk,we added this user to dialout group to have the 
good rights on those files. Problem: we can't open conferences, we 
always have

[Mar 30 10:55:37] WARNING[28302]: chan_zap.c:896 zt_open: Unable to open 
'/dev/zap/pseudo': No such device or address
[Mar 30 10:55:37] ERROR[28302]: chan_zap.c:7631 chandup: Unable to dup 
channel: No such device or address
[Mar 30 10:55:37] WARNING[28302]: app_meetme.c:758 build_conf: Unable to 
open pseudo channel - trying device
[Mar 30 10:55:37] WARNING[28302]: app_meetme.c:761 build_conf: Unable to 
open pseudo device


What's wrong? The B410P being a Digium card should gave us a timing 
source? Do we forgot to compile some module (no one wxxx from zaptel 
directory is activated)? More generally, how you get the timing working 
with B410P cards and 1.4?

We tried another way, ztdummy: by loading the module, the meetme 
application start to work but ... no more audio in all applications 
(voicemail, meetme, MOH, echo-test, demo,...)! In log we found

Removing ztdummy give audio back but no more meetme :-(

Before opening a bug, we would like to know if some of you have a similar working setup with B410P and meetme.

Thanks for your feedback.
