1.4.11 / 1.4.13 differences and why?

The other day I upgraded our 1.2 asterisk to 1.4.13. There is a 1.4.11 server with a tdm400p card, configured, attached analog phone, zaptel, zapata and extensions (workable for testing) working properly.

Okay, it took forever to get zaptel 1.4.5.1 to install properly (3) times. Asterisk installed properly. Copied over the zaptel, zapata, and extensions.conf files over to this new server.

  1. no dial tone from attached analog phone

  2. and no inbound/outbound/console dialing to and from the analog phone.

Everything is working on the 1.4.11 server just fine with the same files why does it not work for 1.4.13 server?
