When I was with another provider, I was able to add custom caller ID entries for Restricted/Blocked numbers, and the custom caller ID information would show up (most of the time) when the caller called us instead of Blocked. I noticed that things did not work this way with voipo and asked and the said that they cannot support that. I'm just wondering why this worked and what would be required to support it with Voipo. The blocked number is a POTS line with Embarq. For now, I've just programmed in our number with the unblock code before it.
