Resolved issues

The following table lists the issues we resolved in VidyoGateway version 20.2.1.

VidyoGateway Version 20.2.1 - resolved issues




An issue that caused SIP header additions to stop working has been resolved.


An outbound dialing issue was fixed, therefore calls to cell phones can now be established with audio in both directions.


An issue that caused some customers to be unable to hear DTMF tones from the Vidyo endpoint or gateway has been resolved.


Using Far-End Camera Control with H.323 endpoints now works faster.


When a SIP proxy password is added via the UI, it now properly gets reflected in the main SIP configuration. Previous upgrades would modify the password so it would need to be manually re-entered.


IP addresses that use the "/" character, such as those used for a whitelist or blacklist, are now accepted.


Inbound calls no longer fail if endpointModel uses the "~" character.


When configuring a SIP proxy with an FQDN or IP, the SIP proxy FQDN/IP is now correctly appended as @domain to the dialed digits.


SIP/H.323 calls are now being disconnected as expected when the conference room is full.


An issue was addressed where a process could get deadlocked when malformed messages were processed.


The ability to mute video options via DTMF is now available when "Enable Video Control Keys" is selected and not when "Enable Audio Control Keys" is selected.
