When I tried to record a voicemail, my phone unregistered

I have a grandstream 2000. I was trying to record a voicemail for the phone. I thought the password was 12345. I attempted with this password twice and then I noticed I got unregistered. Am I locked out now? Is what normally happens if you put in the wrong password and will this work itself out? I also re-registered the phone in endpoint manager. Please advise! Thanks
