Hi Ashling,
If you want to auth with ser your ser.cfg must be like the above ... with the auth and auth.so modules umcommented. Take a Look and see if it helps you ... be in touch if anything goes wrong.
----------------------- ser.cfg -------------------------

# yes, it is good for trouble-shooting
#sip_warnings=yes
# server_signature - Should locally-generated messages include server's
# signature? By default yes, it is good for trouble-shooting.
# server_signature=yes
# reply_to_via - A hint reply modules whether they should send reply
# to IP advertised in Via. Turned off by default, which means that
# replies are sent to IP address from which requests came.

# multihomed servers.
