Hi,
I've the same problem. I've a fresh installation of Trixbox 2.0Beta and
vISDN visdn-0.18.0.
All the calls to and from Trixbox work well and no noise is heard.
I've noted that if I unplug the Isdn S0 cable from my Trixbox the noise
heard by the remote site disappear.
I've a NT1+ with connected an Isdn Phone and an analog phone on the a1
port. I've tried to use a shielded utp cable long about 50 cm but the
problem persists.
I tried to comment ztdummy in /etc/sysconfig/zaptel but the problem
persists.
Any ideas?
Is it normal that if i issue a debug visdn q921 i dont see any messages?
I've noted that if I reboot the pc that is running Trixbox and I don't
make any voip calls through the vISDN trunk, the problem disappear, but
after the first transit on the trunk the noise problem returns.
This is my vIsdn.conf
