[Asterisk-Users] how to make sip uri work

[Lee Goodman]

Lets say I have an * at my business, with 7960 SIP phones. All the sip
phones are registered using their extension number (like 305), but I would
also like to put my SIP URI on my business card and in a name format, not an
extension number (like lee.goodman), so that the SIP URI would read
lee.goodman at asterisk.company.com.

How would I set this up in extensions.conf?

I got 305 at asterisk.company.com to work

If I have this extension

exten => 305,1,Dial(SIP/305,16) ;Lee Goodman
exten => 305,2,Voicemail2,su305
exten => 305,3,Hangup

would I have the following as well

exten => lee.goodman,1,Dial(SIP/305,16) ;Lee Goodman
exten => lee.goodman,2,Voicemail2,su305
exten => lee.goodman,3,Hangup

when I try this, it looks like it trys to go to voicemail (my 305 phone is
not registered) but it hangs up first


Thanks
