asterisk users - Jul 2003 - conference problem without zapata interface

Hello !

In file app_meetme.c we can read
A ZAPTEL INTERFACE MUST BE\n"
"INSTALLED FOR CONFERENCING FUNCTIONALITY.\n"

I receive message, when I try conference
WARNING[28686]: File app_meetme.c, Line 151 (build_conf): Unable to open 
pseudo channel
    -- Playing 'conf-invalid'


Does it means that I cannot establish conference without
any hardware zaptel interface ???

What can I do if I want make conference only between my sip phones 
using asterisk ??  Buy it ???

Greeting 
Andrzej Radke

No.

Yes.

Alternatively, you get the zaptel drivers, edit the Makefile to build
'ztdummy' (remove the '#' before ztdummy on the line just after
the line
starting with MODULES), compile, install, and do modprobe ztdummy. Why
this would help can be found in the archives (just as this answer) and
is left as excercise for the reader.

wkr,

You need to load the ztdummy kernel driver.  It will provide the pseudo
timing needed to sync the conference channel.

It is a driver that creates a dummy Zaptel hardware interface.
