You just about answered your own question here, different codes for each
manufacturer is not equal to standard. Asterisk has support for analog
phones, and digital trunking via E1/T1 circuits. This allows you to
interconnect to phone systems that might use digital phones. You can
also use it via a channel bank to link large amounts of lines to
asterisk.
