\page chan_sip3_todo Chan_sip3: Things to do
\b Done
+ - Trying to reduce memory allocations for packets.
+ - sipsock_read allocates a packet that stays in memory
+ until the transaction is finished. If it's an initial
+ request, it's flagged to stay in memory and kept until
+ destruction of the dialog (or replacement of initreq).
+ - The issue here is parsing, since parsing destroys the
+ in-memory copy of the outbound message thus stopping
+ proper re-transmits. Added flag for parsing of packet,
+ trying to delay parsing until we send a response.
+ - Added new CLI command "sip list configs" to list all configuration options
+ Mostly for debugging
+
+ - Added new configuration engine
+ - Add T1 timer configuration settings
+ - Added configurable T2 timer, see \ref sip3_timer_doc
+ - Added time to astdb registry storage, so that expired registrations
+ won't be activated at restart
- removed pedantic mode
- added config option for qualify frequency timers
- merged peermatch and sipregister branches
@@ -156,11 +185,36 @@
- T38 does no longer depend on canreinvite settings
- removed userconf support (in favour of astum)
+ \b Larger changes required outside of chan_sip
+ - dnsmgr needs to follow DNS ttl
+ - dnsmgr needs to handle SRV, NAPTR
+
\b Halfdone
- Added separate TOS setting for presence. Need to run setsockopt
in a locked socket for that to work on the SIP interface.
- \b Todo
+ \par Todo - architecture
+ - check if the "defaultport" and "port" settings are working - port for remote peer?
+ - dnsmgr needs to be integrated and updated
+ - netsock?
+ - thread and separate port for outbound registrations
+ - receive queue between sipsock_read and handle_request
+ - inbound call authentication
+
+ \par Todo - ideas
+ - Implement support for a:rtcp sdp (needs changes in the rtp interface)
+ - Implement "busylimit" for signalling busy, but not enforcing a call limit
+ - Use "accept-language" to set language tags in error messages etc
