[SR-Users] Bad event error with an incoming PSTN call...

Hello,  I am trying to make an incoming PSTN call to and extension connected to Kamailio. I have set up the db_alias module and I have allowed the gateway to bypass the authentication. When I try and make a the call from the PSTN line I keep getting a 489 Bad Event error. Can someone let me know what the problem could be, thank you. My output is as follows: U 2013/07/14 21:15:59.265174 10.243.63.204:5060 -> 64.136.xxx.xxx:5060 SIP/2.0 403 Not (AJ Test 01) Allowed.
