We use two gatekeepers to maintain failover, so for each gateway, I confiugre like:
ip address 10.0.56.31 255.255.255.128
h323-gateway voip interface
h323-gateway voip id GK1 ipaddr 142.x.x.11 1719 priority 120
h323-gateway voip id GK2 ipaddr 142.x.x.139 1719
h323-gateway voip h323-id SQPSTN1
h323-gateway voip tech-prefix 1#
h323-gateway voip bind srcaddr 10.0.56.31
This works well when one gatekeeper is down, gateways will register with second gatekeeper. However the problem is, all gateways take over 15 seconds to failover to second gatekeeper. The default register retry and timeout are too long, so I use:
ras timeout grq 3
ras retry grq 1
But this doesn't work, re-register still takes over 15 seconds.
