3rd Message : 401 Not Here

Looks like we are missing something in the configuration file for kamailio. Can you please guide us through the process so that we can get this working. I am attaching my kamailio.cfg file with the mail as well as the ethereal captured log file in format of .jpg file with the mail.

We also want kamailio to listen on multiple ports such as 5060 and 5062 and we have made according changes in the configuration file as well. Please have a look at those as well and tell us whether we are doing it right or not. Also if you feel that we need to do some additional changes in configuration file. Please suggest them.

PS: Attachments (EthCap.jpg and kamailio.cfg)
