[Asterisk-Users] Problems w. chan_capi + ztdummy

[Lars Boegild Thomsen]

Hi Everybody

I've got a weird problem.  I am running one Asterisk system on a dual
processor box.  This box mostly do VoIP only but it has a Fritz PCI ISDN
card installed with latest drivers.  Dialing out through the ISDN cards from
an internal Snom phone works fine and so does dialing in.  Except - if I
load the ztdummy module (for IAX channels) the capi drivers starts acting
up.  It is hard to describe the sound but it breaks up so badly that it is
impossible to understand the voice prompts and they also start playing
extremely slow (demo congrats alone takes more than 30 seconds before going
to the next prompt in the standard demo setup).

I am nearly updating this particular box every day and within the last
couple of days something else has happened.  When dialing OUT on the ISDN
card everything works fine.  When someone dial IN through the card and
connect to the internal Snom phone there is a pulsating background noice
that can only be heard on the VoIP phone.  From outside (the ISDN) things
sound perfect - from inside you can still hear what is being said - but
there is that pulsating quite high noice.

Any ideas?

Regards,

    Lars...
