Route Outgoing calls through ISDN using Specific Channels

Route outgoing calls through ISDN using specific channels based on the Calling party’s number.
 
 
                                ISDN 14 channels
(1002) Phone  —- CUCM ———- GW ===================== Telco – Phone (2002)
(1003) Phone
 
Issue : When Ext 1002 makes outbound call, Call should go out through First 1-10 channels and when Ext 1003 makes call, channels 11-14 should be used. 1002 should not be able to use channels 11-14.
 
Following cmds needs to be issued on the Gateway :
