You  should not use a DID range as Gatekeeper tech prefix The technology prefix should not be used as part of the actual routing of the DNs. The purpose of the field/config is to create groups (Example ) ie 1# are GWs 2# are video enabled GWs 3# are cucm trunks This are then added to the number you dial and stripped by the GK. You should take care of your routing using the zones configuration in the GK and not to rely in the tech prefix as an actual part of the DN you're trying to reach. Here is an Example  but just the basics so you understand the high level concepts. I'll just show 1 route pattern, create as many as needed. use tech prefix as 1# for all systems In CUCM register the GK RP with DN 4[67]...

I guess there is only one option :-( Device>> Gateway >> PRI >>Setup non-ISDN Progress Indicator IE Enable Check this box and reset the gateway. Here is a brief explanation of the feature: Enable this setting only if users are not receiving ringback tones on outbound calls. When this setting is enabled, the Cisco Unified Communications Manager sends Q.931 Setup messages out digital (that is, non-H.323) gateways with the Progress Indicator field set to non-ISDN. This message notifies the destination device that the Cisco Unified Communications Manager gateway is non-ISDN and that the destination device should play in-band ring-back. In this case if the gateway has to paly the dial tone locally we would  have to change the switch type to a different one. As I  have noticed it earlier the switch type in use qsig does not  offer this option. ... View more
