I have (3) GKs. I have everything working correctly. Each GK has it's Tech-Prefix or type-prefix.
Off of each GK I have a couple h323 GWs. They have Tech-Prefixes also to
GK-A
gw-type-prefix 1#* default-technology
GK-B
gw-type-prefix 2#* default-technology
GK-C
gw-type-prefix 3#* default-technology
GWY-A
h323-gateway voip tech-prefix 1#
(this would then go GK-A)
GWY-B
h323-gateway voip tech-prefix 2#
(this would go to GK-B)
GWY-C
h323-gateway voip tech-prefix 3#
(This would go to GK-C)
Do I need to add the other tech-prefixs to each of the other GKs?
Example
gw-type-prefix 1#* default-technology
gw-type-prefix 2#*
gw-type-prefix 3#*
I'm guess I only need to use tech-prefix when I have a h323 end point such as a GWY or CUCM cluster correct?
Thanks much!

A technology prefix identifies H.323 endpoints by type or class or identifies a resource pool to the gatekeeper. It is important to configure a default technology prefix on the gatekeeper and a technology prefix on the gateway for everything to work correctly. Select a technology prefix to identify the type of gatewayin this case, a voice gatewayto the gatekeeper
Defining a technology prefix is important for proper operation because in most cases, calls do not route properly if this step is not done. Typically, the called number matches a zone prefix, not a registered E.164 address. In this case, if a technology prefix is not also matched, the call is rejected

Thanks Marwan .
So are my configurations correct or did I go overboard on the prefixs?
Thanks much!

u can either leave to defualt and use the zone prefix to control the call transfere betwen GWs and GKs
or u could use gw-type-prefix as a area code for example for that zone or gateway instead of configuring zone prefix on the GK
for example
u wanna calls come to KA to start with 444 to be send to GWA
configure GWA to rigister with GKA and configure the gw-type-prefix like
h323-gateway voip tech-prefix 444
then check on the GK b useing
show gatekeeper zone status
show gatekeeper endpoints
Display the technology prefixes registered with the gatekeeper. Enter the show gatekeeper gw-type-prefix

Thanks buddy!
Hey quick question, have you ever seen a phased migration of GWs to GKs work? I cant seem to figure out how a phased migration would work?! If my existing GWs are using Dial-Peers to/from other GWs, the only way I see of moving the GWs to the GKs is to do a flash cut. (move all GWs to the GK at once)
cheers!

Hi Marwan,
According your answer, Should tech-prefixs and full technology be used when you wouldn´t set the zone prefix on GK?
Shall I set all prefix in all Gatekeepers on the network (gw-type-prefix 1#*, 2#* and 3#*)?
