Release notes for SIP Express Router (ser) *********************************************** $Id: NEWS,v 1.15.2.1 2003/08/27 07:57:08 calrissian Exp $ *********************************************** * Changes introduced in 0.8.11 *********************************************** +--------------------------------------------------------+ | CAUTION: the 0.8.11 release include changes which | | are incompatible with scripts and databases used | | in previous versions. Care is advised when upgrading | | from previous releases to 0.8.11. | +--------------------------------------------------------+ New features ============= - RFC3261 support - TCP support and cross-transport forwarding [core] - loose routing support [rr module] - New modules - vm -- voicemail interface [vm] - ENUM support [enum] - presence agent [pa] - dynamic domain management -- allows to manipulate hosting of multiple domains in run-time [module] - flat-text-file database support [dbtext] - rich access control lists [permissions] - Feature Improvements - click-to-dial, which is based on improved tm/FIFO that better supports external applications [tm module] - web accounting -- acc module can report to serweb on placed calls [acc module] - improved exec module (header fields passed now as environment variables to scripts) [exec module] - Architectural Improvements - powerpc fast locking support - netbsd support - 64 bits arch. support (e.g. netbsd/sparc64). - New Experimental Features (not tested at all yet) - nathelper utility for Cisco/ATA NAT traversal [nathelper] - another NAT traversal utility [mangler] - postgress support [postgress] - pdt module (prefix2domain) [pdt] Changes to use of ser scripts ============================= About Multiple Transport Support -------------------------------- SER now suports multiple transport protocols: UDP and TCP. As there may be UAs which support only either protocol and cannot speak to each other directly, we recommend to alway record-route SIP requests, to keep the transport-translating SER in path. Also, if a destination transport is not known, stateful forwarding is recommended -- use of stateless forwarding for TCP2UDP would result in loss of reliability. core ---- - reply_route has been renamed to failure_route -- the old name caused too much confusion - forward_tcp and forward_udp can force SER to forward via specific transport protocol acc module: ----------- - radius and sql support integrated in this module; you need to recompile to enable it - acc_flag is now called log_flag to better reflect it relates to the syslog mode (as opposed to sql/radius); for the same reasons, the accounting action is now called "acc_log_request" and the option for missed calls "log_missed_calls" - log_fmt allows now to specify what will be printed to syslog auth module: ------------ - auth module has been split in auth, auth_db, auth_radius, group group_radius, uri and uri_radius - all the parameters that were part of former auth module are now part of auth_db module - auth_db module contains all functions needed for database authentication - auth_radius contains functions needed for radius authentication - group module contains group membership checking functions - group_radius contains radius group membeship checking functions - is_in_group has been renamed to is_user_in and places to groups module - check_to and check_from have been moved to the uri module im module: ---------- - im is no longer used and has been obsoleted by TM exec module: ------------ - exec_uri and exec_user have been obsoleted by exec_dset; exec_dset is identical to exec_uri in capabilities; it additionaly passes content of request elements (header fields and URI parts) in environment variables; users of exec_user can use exec_dset now and use the "URI_USER" variable to learn user part of URI - exec_dset and exec_msg return false, if return value of script does not euqal zero - exec_dset takes an additional parameter, which enables validation of SIP URIs returned by external application jabber module: -------------- - presence support for Jabber users is enabled loading the PA module and using handle_subscribe("jabber") for SUBSCRIBE requests to jabber user msilo module: ------------- - m_store has now a parameter to set what should be considered for storing as destination uri. This enables support for saving the messages on negative replies. radius_acc module: ------------------ - radius_acc module has been removed and radius accounting is now part of acc module registrar/usrloc modules: ------------------------- - multi domain support, the modules user username@domain as AOR if enabled - descent modification time ordering of contacts - case sensitive/insensitive comparison of URI can be enabled rr module: ---------- - addRecordRoute has been replaced with record_route - rewriteFromRoute has been replaced with loose_route() - a new option, "enable_full_lr" can be set to make life with misimplemented UAs easier and put LR in from "lr=on" - rr module can insert two Record-Route header fields when necesarry (disconnected networks, UDP->TCP and so on) tm module: ---------- - t_reply_unsafe, used in former versions within reply_routes, is deprecated; now t_reply is used from any places in script - t_on_negative is renamed to t_on_failure -- the old name just caused too much confusion - FIFO t_uac used by some applications (like serweb) has been replaced with t_uac_dlg (which allows easier use by dialog- oriented applications, like click-to-dial) - if you wish to do forward to another destination from failure_route (reply_route formerly), you need to call t_relay or t_relay_to explicitely now - t_relay_to has been replaced with t_relay_to_udp and t_relay_to_tcp
