Asterisk load contact into sip client

Hi, I’m new using asterisk, it has been only 3 weeks. I have asterisk version 11.3.0 install on Ubuntu.
I would like to know if it possible to load my contacts in sip client after a user authentication so if he needs to make a call he wouldn’t have to remember the extension and if I have to set up new extension it would be easier to set up the phone book.
thanks for any help.

If you were able to load this information using SIP, the device would be acting as a SIP server (the roles are reversible). However, I don’t believe that there is a SIP method for doing this, so you would need to consult the documentation for the phone in question. Normally this information is distributed during the booting sequence for the phone, before it registers, and will use a TFTP or FTP server, rather than the moain PABX.

Asterisk does have some support for this for Digium phones, but I haven’t investigated this yet.
