Alphacom tests all UDP ports used for RTP audio (61000 - 61128 ) regularly. Every 3 second, it will allocate a port not in use, and open it for 1 second. If any packets are received during that second, it is considered an error, and the following message will be sent to syslog:

N051.D066: UDP port 61114 (channel 57) receive 100 unexpected packets from 10.5.202.12 in idle. Keep channel out of use.

The port is taken out of use until it is tested again. The idea is that this is an indication that some external device is stuck in a state transmitting to AlphaCom, and that port can therefore not be used.

In a MultiModule system the UDP ports of the slave modules are also tested.

To disable, use TST#NVRAM editor to set

.ex_profile.timeouts.iech_test_timeout = 0

New in AMCD 10.61.
