[asterisk-users] AMR - Segmentation Fault

[Giacomo Vacca]

Hi Chandrakant,
for what I can see the patch you're trying to use (
http://sourceforge.net/projects/aterisk-amr/files/) is going to work with
1.8.13 as well, however the issue behind the crash is not in Asterisk's
code but in 3GPP's original AMR implementation when running on 64-bit hosts.
I've found that applying the patch suggested here:
http://lists.digium.com/pipermail/asterisk-video/2008-October/002229.html to
codecs/amr/typedef.h fixed the crash.

I hope this helps and I'd be interested to know if this solves your issue.

Regards,
Giacomo
