Xii.3.2 When Connecting Two Audiocodecs In Unicast, There Is No Audio At One End - Prodys PortaNet User Manual

Each firmware version might have a different OCX file, so the new OCX should be
installed as it is done for the first access to the web page of the unit. If the unit
was upgraded and, depending on the 'cache' configuration of the Internet
explorer, there might be problems when accessing the web page, given that the
old web page might be offered by the browser instead of the real one, which
should be installed to replace the old one. In this case, a message indicating
'Incorrect Versions' will appear as soon as the user click on 'Control' or 'Monitor'
on the login page. Click on F5 to skip the cache entries, and access to the 'real'
web page. Even after pressing F5 and, depending on the IExplrorer configuration
and/or version, this situation might continue. In that case, go to Internet Options
in IExplorer, click on 'General' tab, and delete temporary files.
Windows Vista: Should the user experience a problem when downloading the
OCX file when first accessing the web page of the unit, please disable UAC (User
Access Control) on Windows Vista. Once the OCX file has been installed in the
computer, UAC can be enabled again.
XII.3.2 When connecting two audiocodecs in unicast, there is no audio at one
end.
Please check the enabling of the full TCP port range ("Base port" + following 30
ports) of any router or firewall between the audiocodecs. Hint: start checking
from the disturbed audiocodec on.
