I am trying to host a conference, but one of participants is unable
to join. He always receives the answer that the conference number is
invalid...
It is likely that the person's phone system is
blocking outgoing DTMF (dialtone) signals, making it impossible for the
person to enter the conference number. (Therefore he always receives
said answer after a timeout) Please consult the 'Frequently Asked
Questions' section for a solution.

I'm using XLite 2.0 under Linux and sometimes after a call, sound
crashes and won't work anymore, until the program has been restarted...
Apparently
this happens, when XLite sometimes doesn't get the information about the
hangup from the other side. Try to make sure that after a call XLite
ends up in 'Hungup' state and the line is no longer indicated as being
used.

My Nokia E70/N95/... won't register with the IFI VoIP Server...
There
are a couple of catches with the Nokia VoIP Client configuration: For
instance the login information should be entered in the 'proxy server'
part and not in the 'registry server' part, and the realm (which might
eventually be reconfigured to 'ifi.uzh.ch' on our behalf) setting should
be 'asterisk'... more information (a.o.) here, or by
searching google (Nokia N61 asterisk)

I've configured my account to ring at an external PSTN phone number
(e.g. my cell phone) when I'm called... but it won't work...
At
the moment, an additional prepended '0' is required for this to work
with external PSTN numbers (see 'Issues' page). This will eventually
change, when this issue is solved.

My calls are being dropped after a short time of conversation.
Check your VoIP client configuration for automatic disconnection. In
X-Lite for Windows, for example, make sure the check box shown below is
unchecked in the Options window, under Network, Call Inactivity. The
software may disconnect your call even if there is activity.
