Description:I have a dual Xeon system with 2 B410P cards, sound (voicemail, demo, ...) is working well. Now I want to run meetme on this server.

When I load zaptel for timing source, all the stuff is created in /dev/zap/channel|ctl|pseudo|timer|transcode but meetme still complains that he can't found /dev/zap/pseudo (user asterisk is added to group dialout). I then load ztdummy, meetme application start without complain about missing device (see it from logs) but no more sound in all applications, including meetme. Those are logs I get:

Mar 29 22:40:36 SrvPhone kernel: Zapata Telephony Interface Registered on major 196
Mar 29 22:40:36 SrvPhone kernel: Zaptel Version: SVN-branch-1.4-r2351

Mar 29 22:40:39 SrvPhone kernel: rtc: lost some interrupts at 1024Hz.

Mar 29 22:42:11 SrvPhone last message repeated 3050 times
Mar 29 22:42:57 SrvPhone last message repeated 2348 times

Removing ztdummy, audio is back. Two possibilities:

.this a bug in ztdummy (with B410P?)
.this an incompatibility between ztdummy/mISDN/B410P

In the last case, how to get then timing source with B410P so meetme application works?



tested with Asterisk 1.4 & zaptel SVN as well as 1.4.2/zaptel 1.4.1, kernel as well as from Debian Etch. mISDN is 1_1_1 from misdn.org In misdn-init.conf, I have option=1,master_clock

I think the main issue is that Meetme can't use B410P cards' timing when it should  As with other Zaptel cards, ztdummy should not be loaded if a zaptel card is present in the system.

I agree with you, ztdummy was our last possibility to try to get it work. What do you propose?
