If you have access to Quintum dociments, please take a look in
“Quintum_GAtekeeper_Architecture.pdf”. Ther is some contradictory explanation.
I am not sure that I understand it:
SO you can use A400 as MASTER, but only 4 IP call can be done concurrent.!!!!
Structuring Very Small Networks (Maximum of 4 Tenors)
Very small networks consisting of no more than four Tenor gateways can be designed using one of the
Tenors as the network manager without the need for an integrated or standalone gatekeeper. Every
Tenor gateway has the ability to manage such a network. When designing such a network it is only
necessary set the Border Element IP address in each “slave” Tenor to the IP address of the “master”
Tenor. In this way the master Tenor will act as the Border Element for the small network. The Border
Element will build a table of all the DN’s and IP addresses for each of the Tenors in the network and will
replicate this information out to each Tenor.
The call capacity of the master Tenor should have enough ports to support the desired number of calls in
the network. For non-blocking configurations the number of ports should be equal to the number of
phones in the network. The number of ports that can be supported by a Tenor is equal to the number of
VoIP channels. This means that a Tenor A400 can support up to 4 VoIP calls and thus has 4 ports
available. A Tenor D1600 can support up to 16 VoIP calls and thus has 16 ports available. A Tenor
D3000 can support 30 VoIP calls and has 30 ports available.
In general the Tenor with the smallest call capacity should be used to manage the network. This Tenor
will generally be the lightest loaded and will have the most spare memory available for storing the
complete network database. In the example below the Tenor A400 would be used.
