[Freeswitch-users] DNS cache on invite/register

[Michael Jerris]

if they are doing nonces on a shared realm, they should be sharing those nonces across their cluster.  If they are not, every time it hits a diff member of the cluster you will get a stale nonce and have to go through that juggle again.  This is just a side effect of how sip auth works.
