[asterisk-users] sflphone questions

[Tom Poe]

I want to set sflphone as extension on asterisk.  I have a sip 
account/DID with vitelity.net.  Not sure what to put in the wizard:
alias  ??? 
hostname ???  is this the asterisk server hostname, or the hostname 
where my sflphone is sitting on the lan (it's a home network)
username ??? is this the assigned extension number?
password ??? is this the assigned extension number password?

Any help appreciated.
