[asterisk-users] Asterisk 1.6.2 ?

[Ben Dinnerville]

This is usually due to an error with the SIP stack not being loaded due 
to an error - make sure that full logging is on and check your log file 
and search for ERROR and see if there is any mention to SIP (chan_sip.o 
etc), alternatively, start asterisk from the command like with asterisk 
-vvvvvvvvvdddddddddc and watch the output to screen for any errors at 
startup. Fix the error and SIP will start up.
