Thanks Omonat,
I have used the 8+TG number (e.g. 830), used TIE line access prefix (i.e. 7), leading digits in the TIE table (i.e. 2 and 3) but still hasn't worked. Not sure if the Cisco engineer has some more configurations to do or tidy up or am the one missing out on something..... I did run some traces and see the reports below:

I will appreciate any help please especially from those who may have done this kind of configuration before.
Many thanks in anticipation.
