I am using LCR module to send outbound calls to my carrier, however I am using a new carrier who require authentication. Any ideas on how to authenticate the call to the carrier?

In general, you should try to avoid this scenario if possible, since it's not exceptionally well-supported in Kamailio. But if you must do this, the 'uac' module does offer you a means of responding to authentication challenges:

You can also use an in-line B2BUA, such as SEMS (with its 'sbc' module), for easier handling of this and other complications which might arise.
