[Serusers] Mediaproxy error

[Terry Mac Millan]

Good day,
I have a very interesting error coming back with my attempts to use the
mediaproxy module.
This is what is appearing in the syslog file:
Mar 3 13:26:37 hostthe3rd /usr/local/sbin/ser[30021]: error:
mediaproxy/sendMediaproxyCommand(): can't connect to MediaProxy
Mar 3 13:26:37 hostthe3rd /usr/local/sbin/ser[30020]: error:
mediaproxy/sendMediaproxyCommand(): can't connect to MediaProxy

The phones do ring, but no voice channel is established. 2 phones are
located behind a nat firewall on the same subnet, and the ser server is on
the internet with internet ip's.

I can send a full copy of my cfg file if needed, but will attach small
snippits of it that have the sections on the mediaproxy parts.

Any help on this would be greatly appreciated.

Thanks
Terry
