[Asterisk-Users] kiax - iax2 softphone

[undrhil.1528785 at bloglines.com]

Has anyone on here used kiax before?  I am asking because I have it installed
on several computers and have been able to get it to connect and register
to my Asterisk box.  I can even call between them and my SIP softphones. 
The problem I am having is this: when I use kiax to call someone else, they
get some kind of background music playing while I am talking to them.  I have
called from kiax to kiax phone and get this on both ends but I cannot identify
what it is or where it's playing from.  I've watched the CLI when I make the
call and there is no indication of playing music on hold or background music.
 The dialplan doesn't even reference music on hold, it just dials whichever
phone I am trying to call.

So, I am wondering if this is something which
I need to set in kiax and if anyone who has used kiax might be able to give
me a hint on where I can disable this at.  I would prefer to use an IAX softphone
since it only requires one port to be open into my firewall, but kiax is the
only one I've found for free.  Once I get Asterisk up and running properly,
I'll probably buy a couple of licenses for a good quality softphone, but until
then, free is the best for me.  :)

So, any ideas?
