The

Check that the Ethernet cable is connected
The
icon is not displayed
Check that the SIP account parameters are entered
properly, especially the password.
Make sure that a firewall is not blocking the SIP protocol;
try to change the “Server SIP port” (AETA server).
The link seems to establish, but the decoder does not sync
or the link is dropped after a while
Disable STUN, or conversely enable it.
Make sure that a firewall is not blocking the protocol or
the RTP port.
The audio stream is very disturbed
If the quality meters show a poor transmission quality:
Use the settings proposed above (page 17) to increase the
robustness of the transmission.
Decrease the transmission bit rate (this can be efficient when
the network access has a limited capacity).
You can’t change the bit rate during the connection
(shortcut
Fn
+
2
(
IP/Rate
))
Setting the bit rate “on the fly” is a feature only available with
OPUS. This implies that the remote unit must support this
coding algorithm.
Besides, only another AETA codec is able to “follow” that
during the connection, and change on its side the bit rate it is
transmitting.
The “Transmission Quality” meter does not show up
You can see the “Reception Quality” indicator but the
“Transmission Quality” meter is absent (“?” instead of the
bargraph):
This measurement requires the remote device to support the
RTCP protocol, and this might not be the case.
Check also that the RTCP port is not blocked by a firewall (its
number is that of the RTP port + 1).
