Rich media session Licenses

Question

I have 80 rich media session licenses for jabber guest deployement
2 expressway-c
2 expressway-e
if i install 20 licenses in each expressway how it will work
Please explain

Answer 1

Maybe easier to understand, to say that it will utilize 2 RMS (or traversal call licenses if it would be a VCS).
One on the -E and one on the -C.
So only the ones which are active in a call will utilize licenses.
(here "each expressway" would be 4 licenses, which is not what happens ;-)
In this JG deployment it makes sense to distribute licenses 50:50 in between the -E and the -C.
Expressway does not really know a model like "active/standby". (ok you could put
one of each cluster into maintenance mode, but thats in general not what you want to do).
I tried to find out a bit more how expressway clustering should behave regards jabber
guest, but I did not really find anything, looks like its just RR A records, ...
Within a cluster licenses are shared, so the -E or -C cluster can have allover 40 calls and
as Patrick wrote it does not directly matter how they are distributed.
With 4 expressways I would distribute 20 licenses on each peer, so also 50:50 on peer1 and peer2.
