Managing Polycom MCUs and Endpoints with GnuGk
Problems with MGC firmware 7.5.2 and later
Starting with ver 7.5.2 and later and MGC 8.0, the MGC now sends an additional
terminalAlias called dialedDigits containing the gateway prefix.
In GnuGk, the first IP board to register with the prefix registers successfully.
However, the second IP board to register with the prefix is rejected due to duplicateAlias.
To solve this, GnuGk 2.2.7 implements a filter by endpoint type:
[RasSrv::RRQFeatures]
AliasTypeFilter=terminal;dialeddigits
AliasTypeFilter=gateway;h323id
|
This will filter the aliases to only register the alias types specified
(separated by ','). If an alias type as specified in the filter is not
present in the RRQ then it will just registers as per normal with whatever
aliases are provided. In this way you can filter out the duplicate alias item.
When you add these filters without restarting your gatekeeper, make sure you
unregister your endpoints before you reload your configuration.
