Error while loggin from a remote extension through 3g to asterisk => chan_sip.c:28201 handle_request_register:

I set up an Asterisk using asterisk now and freePbx,while my extension is in my network everything is ok but when i try to connect to my server from a remote extension like my cellphone It brings to me this error:

[2016-12-26 11:10:02] NOTICE[3432]: chan_sip.c:28201 handle_request_register: Registration from ‘“3432” sip:100@’ failed for ‘’ - Wrong password
But I am putting the right password .
I don’t know why this happens

If the password is right the user name must be wrong. I note you seem to have an excess pair of double quotes.
