Managing Polycom MCUs and Endpoints with GnuGk
The GNU Gatekeeper works very well with most H.323 products from Polycom. See below for a list of tested devices.
Usually you won't need any spcific config settings, except for one issue with some MGC devices where you need to set a switch as noted below.
Special issue with MGC firmware 7.5.2 and later
Starting with ver 7.5.2 and later, the MGC sends an additional
terminalAlias called of type 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, use a filter in your GnuGk config 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.
