uri==myself is a destination test, it does not care about where a call
originates from.

There is some misunderstadning here. myself is not related to the number, it
tests domain. (like with email -- it doesn't care about 888 in 888 at iptel.org,
it cares about if iptel.org is owned by the server). The options are then:
- 209.242.10.153 is IP of your host, then the request belongs to the server
  and uri==myself returns true; you can then do whatever you want to do with it
- if it is not your host, uri==myself will return false and you should
  forward the request there

I'm puzzled -- did not you want to transfer to vm after the time expires?

see bellow, I think that should work.

presumably at the same place and in mysql database as well.

YOU REALLY WANT TO HAVE THIS HERE
                           break; /* we are done with INVITE */

THE SAME STUFF LIKE ABOVE, YOU DON'T WANT TO t_relay ANYTHING

if(!vm("/tmp/am_fifo","voicemail")){
                                               t_reply("500", "SEMS
error");
                                        };
                                break;
