I have no clue what I am doing wrong. I installed asterisknow and went through the gui setup. I went in and edited the sip.conf and extensions.conf files for a sip user. I was having a problem when I would call in it would tell me that the user for extension XXXX is not available. I went into the users.conf file and edited the host=dynamic string under (the extension setup for user) and changed it to host=(ip address of phone). Now I can call in and the phone rings when I dial the extension. Should I have to hardcode the phones IP address like that? Another problem I am having is that when I pick up the handset on my Grandstream GPX-2000 and dial 8500 for voice mail I get a 404 not found error as well as when I try to dial out I get a 404 error. I am lost and have been unable to find my way out of this hole. Can anyone please help?
