I was not able to use Callcentric star code features except voice mail.
Callcentric's customer service made suggestions to alter the pre configured digitmap for Callcentric we have on Obi.
This suggestion works for me:
(*xx.|*123|**275*x.|[3469]11|1xxxxxxxxxx|<1>[2-9]xxxxxxxxx|011xx.|xx.|(Mipd)|[^*#]@@.)
