I have successfully installed and configured the asterisk, the incoming and the
outgoing calls are working fine, its a tremendous solution :)
Now i want to enable trunking between two asterisk boxes, in the iax.conf i have
put:
[karachi]
...
...
...
trunk=yes
...
...
...
everything seems to work fine but when i load asterisk it says:
--------------
Feb 17 10:59:14 WARNING[18726]: chan_iax2.c:7536 build_user: Unable to support
trunking on user 'karachi' without zaptel timing
Feb 17 10:59:14 WARNING[18726]: chan_iax2.c:7345 build_peer: Unable to support
trunking on peer 'karachi' without zaptel timing
--------------
I tried to install the ztdummy and i succeeded on one of the box but for the
other i am having problems :(
It was missing the kernel-source rpm. I installed the version that i found but
now the first error is still there and when i modprobe ztdummy it gives the
following response.
-------------------------------------------------------
[root@p15162054 asterisk]# modprobe ztdummy
/lib/modules/2.4.25-040218/misc/zaptel.o: kernel-module version mismatch
/lib/modules/2.4.25-040218/misc/zaptel.o was compiled for kernel version
2.4.20-24.9
while this kernel is version 2.4.25-040218.
/lib/modules/2.4.25-040218/misc/zaptel.o: insmod
/lib/modules/2.4.25-040218/misc/zaptel.o failed
/lib/modules/2.4.25-040218/misc/zaptel.o: insmod ztdummy failed
[root@p15162054 asterisk]#
----------------------------------------------------------------------
Any Kind peace of information will be highly appriciated :)

If not, you'll need one, or you'll need to try and get ztdummy or ztrtc to work. Trunking requires a hardware timing source that the Zaptel devices provide... -A.

Remember trunking is only really useful when you have 3 or more calls at the same time between the same two Asterisk systems. Trunking with only one call actually uses MORE bandwidth.

[Asterisk-Users] can't enable trunking :(

Fix the symlink and verify it points to the new kernel sources, then perform a make clean ; make install in the zaptel directory and try reloading the driver. Without a timing source, trunking simply will not work. HTH, Leif Madsen http://www.leifmadsen.com
Sorry if this subject has been covered, but, my boss claims to have a working IAX2 trunking set-up without a timing source on one side of the connection. In all the posts and documentation regarding this subject, this appears to be impossible. My questions are: 1) could this be true? 2) if it is - is there a load limit where it breaks down? In summary, will IAX2 trunking work without some kind of timing source on both sides? Thanks in advance and sorry if this is a rehash. --Doug -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com]On Behalf Of Eric Wieling Sent: Thursday, February 17, 2005 10:45 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] can't enable trunking :( Muhammad Muzzamil Luqman wrote:> I have successfully installed and configured the asterisk, the incoming and the outgoing calls are working fine, its a tremendous solution :) > > Now i want to enable trunking between two asterisk boxes, in the iax.conf i have put: > > [karachi] > ... > ... > ... > trunk=yes > ... > ... > ... > > everything seems to work fine but when i load asterisk it says: > > -------------- > Feb 17 10:59:14 WARNING[18726]: chan_iax2.c:7536 build_user: Unable to support trunking on user 'karachi' without zaptel timing > Feb 17 10:59:14 WARNING[18726]: chan_iax2.c:7345 build_peer: Unable to support trunking on peer 'karachi' without zaptel timing > -------------- > > I tried to install the ztdummy and i succeeded on one of the box but for the other i am having problems :(If you can't install Zaptel (a real driver, ztdummy, zaprtc, etc) then you can't use trunking.
