the scenario is the calls to 936* will go to gw 220.127.116.11, calls to 735 will go to gw 18.104.22.168.
However GW3 (22.214.171.124)is registered with 9#, so when people press 9 the 2nd dialtone, call will go to GW3.
My concern is because I have tech-prefix 9# here, will the calls to 936 also actually will be sent to GW3 because 936 starts with 9? (FYI, the reason we have 9# here is for all the video outbound call, srnd recommends use 9# for that)
Tech prefix is used by gatekeeper for routing decisions. Its not part of the string dialed by the end user. When you setup a phone system such as Callmanager or CME to register to a gatekeeper, you set the tech prefix to be used under the trunk configuration page or under the h323 voip-interface command on a CME router. So when you dial a number such as 936-XXX-XXXX, the string that gatekeeper receives will be 9#-936-XXX-XXXX. It strips the 9# and uses the remaining digits as the destination number. 9# is used to select which gateway should receive the call. When a call to 936 area code is received it truly depends on where the call is coming from and what tech prefix is prefixed in the incoming call setup message.
Look at more details on how a gatekeeper routes a call here.
