I'm not sure it can't be done the same way. Never tried it but it makes sense to me.

Another way I have done it is to remove from the trunk group, program a speed button to dial that dials the Individual Trunk Select code.
The COS has to allow this.

Forgot to mention that am using an analogue phone for this and when try the fac **2 followed by the trunk number 0105 then the external number ( **2 0105 ext number ) it always display the first trunk number even when I removed the trunk from the group

Most T-1 (and E1 also I assume) have a "blanket" outbound caller ID supplied by the telco, no matter what channel you grab you will likely get the same outbound caller ID unless the telco has specifically setup a special outbound caller ID for that channel.

If this is a ISDN-PRI it is handled a little differently, the system sends an outbound caller ID that is programmed in the system on that extension no matter what channel is used, if one is not supplied by the system then the telco circuit ID (main number) is usually substituted no matter what channel is selected.

What protocol are you using ? If it's PRI and you have a range of DID numbers allocated by your Telco, you may have to program CPN substitution using the IMAT Tool.
