[Asterisk-Users] seg fault when accessing voicemail via any IAX softphone (diax, iax phone)

[Amar Maktal]

hello all,

i am happy to be part of the asterisk community. i
have sucessfully configured my asteisk server with the
following (fxo card, fwd-ipkall, fwdout,) everything
works great except when i attempt to check my
voicemail via any iax softphones for windows (diax,
iax phone). basically whenever i attempt to access
voicemail (via demo extension 8500) i get a 
segmentation fault. when it does work there is a
distinct "dong" noise and distortion which occurs when
Comedian Mail is announced. this problem does not
manifest itself when handling iax calls coming from
fwd network. it fails/seg faults 95% of the time. 

i have copied information from my console, confs, and
gdb. *this does not happen with sip clients. nor does
it happen with incoming iax calls (like from fwd).* it
only seems to happen with local, registered, iax
softphones. i am considering purchasing an iaxy but am
afraid that this will continue to happen.

i searched but could not find anything adressing this.
any help would be appreciated. 

running fedora3 core.
my asterisk version (built from cvs):
Asterisk CVS-HEAD-03/03/05-16:05:19 built by
root at localhost.localdomain on a i686 running Linux

here is an entry in my iax.conf for my softphone:
[amarfresh]
username=amarfresh
type=friend
auth=md5
host=dynamic
context=default 
secret=abcdefg
regexten=6969
mailbox=6969		; Notify about mailbox 6969
callerid="Some Host" <(732) 999-9999>


asterisk console crash message:
