ERROR in mediaproxy failed to connect to Mediaproxy

Hi everyone,

I'm trying to connect two NAT clients to a Openser + Mediaproxy machine, but everytime i tried to connect there's an error on the openser:

ERROR:mediaproxy:sendMediaproxyCommand: failed to connect to MediaProxy

I've already verified if Mediaproxy as started, if the module is launched in the openser... everything seems to be in order.
Anyone have any ideia of what could be giving this error. I don't know what else to look for...

Thanks in advance,

Nuno

Here's my mediaproxy.ini configuration (i'm just listening to RTP ports 5190-5194):

portRange = 5190:5194
;TOS = 0xb8

After a couple hours looking at my openser.cfg came across the problem... my path for the proxydispatcher was wrong
Now everything is working fine. It's incredible... but it's true!
