Pjsip reload causes error No authentication username for auth 'dcs-trunk-auth'

I have compiled and installed asterisk, set up a few extensions, when I try to reload the pjsip module I get the errors below. I have also unloaded chan_sip.so in modules.config.

Does that mean that everything is fine, when you start Asterisk initially? If it is usually running in the background, you could seen the initial messages by starting with the -c option. You could also check the log files, but that depends on the configuration.
To me it looks as if your configuration is not complete, so you should post your pjsip config.

i solved it thanks, went through pjsip.conf corrected errors.
