I get a fair number of calls (from friends I have put onto the OBi network) on my OBiTalk service. Their OBi numbers show up in my callerid as 9-digit numbers. I would like to be able to return these calls by pulling up the caller id and hitting the TALK button on my cordless phone. In other words, I'd like to automatically convert any 9-digit number "xxxxxxxxx" into "obxxxxxxxxx" in the appropriate digitmap and hand it off to the OBiTalk service. I could probably cobble something together myself, but figure there may be a more elegant and preferred way of doing this. Any preferred solutions, or should I tackle this myself? Obviously, it shouldn't break anything else, like 7-digit dialing.
