I`m looking to deploy Gatekeepers connecting to GW`s and possible thinking of using "rrq dynamic-prefixes-accept" so reduce administration. The idea is that rather then configure Zone prefix for each Pots Dial-Peer on the local gateways we use the dynamic-prefix-accept setting so dial-peer are automatically added- all good so far particular in a single GK set up . However I`m also thinking of use a back GK and using GUP/ Alternative GK my question is
1.Do I need to configure alternative as below on each GW in my GK cluster so to point to the primary and alternative GK- I though as part of the initial registration process the GW is provided with the alternative so the config. below is not required ?
h323-Gateway voip interface
h323-Gateway voip id NA-GK ipaddr 18.104.22.168 1719 priority 1
h323-Gateway voip id NA-ALTGK ipaddr 22.214.171.124 1719 priority 2
h323-Gateway voip h323-id US-GW1
2. When using GUP, Gatekeeper clustering can I still use "rrq dynamic-prefixes-accept" and not configure any Zone Prefix on either GK- Primary and alternative
3. If I use "rrq dynamic-prefixes-accept" is the fail over seamless or do they have to rebuild themselves again and if so does anyone know what time
