asterisk users - Sep 2003 - MGCP question

Hi List

I have one question about MGCP in asterisk. I have a media gateway, and I
want to have asterisk to work with the media gateway. As I was told that the
media gateway can communicate with the switch via standard interface
MGCP/ICGP. Question is if the asterisk MGCP supports such MGCP message ???

Thanks.

I'm running the CVS from last week and from day one (over 4 months now)
I've had this problem where asterisk core dumps when using chan_h323.

It appears to be a problem with pwlib and the console, but I'm not sure
how to read the below output from gdb. I can start Asterisk just fine
and chan_h323 works great when sending and receiving calls. I only have
this core dump problem when sending a reload to Asterisk via the CLI or
"asterisk -rx "reload"".

Environment paths:
LD_LIBRARY_PATH=/usr/src/pwlib/lib:/usr/src/openh323/lib
PWLIBDIR=/usr/src/pwlib
OPENH323DIR=/usr/src/openh323

Core dump info:

Sure, I tested MGCP with Cisco 3640, 5300, 5400 and ATA phones and works
great. I tested with MGCP 1.0. I don't know if * supports other variant than
1.0.

Regards,

Gus
