[Asterisk-Users] MGCP problem when through internet

[Alejandro Vargas]

I'm using mediatrix mgcp device without problems with asterisk at home
2.0 over the LAN. But now I trying one of this devices through
internet. My firs problem was nat, but I decided to leave this problem
for later and try it through a vpn. I used gvpe because it is very
transparent. The device connects ok but in many cases (I suspect when
the bandwidth is low) the call is droped after a few seconds with a
message like this:

No command found on [192.168.0.105] for transaction 404. Ignoring..

The number (676 in this case) is variable. Isee with etereal that
Asterisk is sending a message of RQNT 404 aaln/1@[192.168.0.105] MGCP
1.0 and the device responds 200 404 OK, but following this, the
asterisk server starts rejecting the packets of the port it were using
to communicate to the device.
