[Asterisk-Dev] Fw: chan_h323 - Segmentation fault (core dumped)

[CW_ASN]

Hi all:

I've got some core dumps when I use chan_h323. I dial an extension using
h323, routed thru an E100P (like a H323-ISDN_PRI gateway). Sometimes *
hangs, sometimes not. The client used for test es SjPhone
(http://www.sjlabs.com/).

This is the data for one core dump:

What is wrong?

Thanks in advance,
