It really isn't the difficulty I'm trying to avoid; it's the familiarity and similarity to the traditional PSTN that I'm trying to emulate. There are plenty of scenarios that come to mind that deem caller ID blocking necessary, especially for those instances when making a one-off call to a coworker, acquaintance, etc. and you don't necessarily want them to have your phone number. So far, I've consulted several older forum postings of similar but not-quite-the-same issues.
So far, I've tried modifying the outbound call routing, digit map, and even the star code profile unsuccessfully.
My first attempt was using the outbound call route:
{(*67XXXXXXXXXXX?):SP2},{(1167XXXXXXXXXXX?):SP2}
(going off the digit map guide linked above, a ? denotes that 10 or 11 digit numbers will be accepted)
(1167 is for use with my rotary phones that don't have a * key)
I also tried using the digit map approach:
(*671xxxxxxxxxx|xxxxxxxS4|1xxxxxxxxxx|xx.):SP2)
I even went so far as to try this in the star code profile:
*67(<sp2>)
All of the above configuration changes were made and tested independent of one another (not all at once).
Put simply, I'm wondering if there is a way to create your own custom star code or even a non-star code (e.g. 1157) to access a different service provider. In essence, dialing *67 is the same as dialing **2.
