New Features in OpenSER 1.3.x

• pseudo-variable (PV) refurbishment – modules can add now writable PVs
• SCTP protocol support
• AVPs and HDRs can be accessed via dynamic index
• while statement support
• modules can register to core to fork new processes for own usage, cleaner server initialization
• modules can fork their own timer process for better performance
• cleanups in utility functions and database API – integrate common functionality into the core, removal redundant code
• bugs – more then 160 bugs reported from the community were fixed
• patches – more then 60 community created patches were integrated
• GNU/kFreeBSD support for systems with a FreeBSD kernel and a GNU userland
• redesign of logging functions – the debugging output has a more consistent and syslog-like format even for stderror
• documentation – many errors in module documentation and code comments were fixed
• new assign operator for avps ”:=” – $avp(name) := value will overwrite the value of any exiting $avp(name), resulting in a new single $avp(name) (delete all $avp(name), add $avp(name)). In addition, $avp(name) := null will delete all existing $avp(name)
• configurable debug level at runtime
• unix socket server implementation removed; the functionality is now provided by the mi_datagram module
• several new pseudo variables

• benchmark - config file benchmarking

• carrierroute - routing extension suitable for carriers

• cfgutils - config file utilities

• db_berkeley - Berkeley DB backend support

• h350 - H350 LDAP implementation

• ldap - LDAP connector

• mi_datagram - datagram transport for management interface (MI)

• perlvdb - Perl virtual database engine

• presence_mwi - Extension to Presence server for Message Waiting Indication

• pua_bla - Brigded line appearance extension for PUA

• pua_xmpp - SIMPLE-XMPP Presence gateway

• rls - Resource List Service implementation (beta – not fully released)

All modules in OpenSER 1.3: http://www.openser.org/docs/modules/1.3.x/

  • ability to reload content from files if this has changed

• dialog
  • the module stores many more details specific for dialogs, making possible to build requests in dialog
  • support for dialog persistence across openser restart

• dispatcher
  • ability to use database as backend for the destinations list
  • ability to auto-detect recovered destinations

  • ability to do load balancing within a set of RTPProxies
  • ability to spoof source IP of NAT ping packets
  • SIP NAT pings follow PATH array
  • NAT pings sending is distributed over the natping interval, instead of sending all at once
  • usage of special timer process to send NAT pings
  • new flag in force_rtp_proxy() to force a symmetric rtp session
  • removed the “rtpproxy_disable” string - you can achive the same by either not defining “rtpproxy_sock” (default NULL) or setting it to empty string
