This bounty is to have SIP registrations done via Asterisk Real Time. As of now SIP registration must be done statically in sip.conf. I am looking to have this added in 1.4.X. If a patch is created for 1.2.X then the bounty will be raised to $125.00. The work must be completed before the release of Asterisk 1.6.X beta.
