Do not worry; these things are a continuous learning process.

302 is just an index; when you define an AVP, you could name it with a
string or with a integer; you choose at your will the integer index or the
string you use; AVP with integer indexes are faster to handle within
OpenSIPS Core; AVP with String names are easier to remember for Script
writer.

You cand find more information about AVP's at:

http://www.voice-system.ro/docs/avpops/index.html
http://www.opensips.org/html/docs/modules/1.4.x/avpops.html

Feel free to keep asking about anything you do not understand well.

Best regards.

Sergio.
