thank you!

Yes, app_meetme needs ztdummy if you don't already have a hardware based zaptel device installed.

Yes. It needs a timing source (ztdummy). ----- Original Message ----- From: "Xu Wang" <xwang@cascotec.com> To: "Asterisk Users Mailing List - Non-Commercial Discussion" <asterisk-users@lists.digium.com> Sent: Thursday, April 14, 2005 10:34 AM Subject: [Asterisk-Users] does meetme need ztdummy> Hello > I don't have zaptel installed, but want to run Meetme.

But, in most cases, it requires a recompile of your kernel (rtc is used by default in most kernels, as most kernels are precompiled to use SMP). Try the following URL for more info: http://www.voip-info.org/wiki-Asterisk+Timer Also note that ztdummy requires that you have a UHCI root hub for your USB. OHCI and EHCI will not suffice. There is also realzap, but that requires setting up the finicky Realtime Application Interface (RTAI). So, realistically, there's four timing sources: - - zaptel - - ztdummy - - zaprtc - - realzap They are required for conferencing (meetme), and IAX trunking. So, I would assume if you don't have a need for either one of those applications, you wouldn't need the timer, and you can safely ignore the warning on startup. A good percentage of offices will require conferencing, however. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQFCXrjRgYKvkeyp3F4RAgqVAJ45C9NSewclcMz+EcJq8D/51BzLhACfYx/S w7vkG8jWWu2Y6C+OLfx8cOo=fBDo -----END PGP SIGNATURE-----
