After about eight months of development, including two months of extensive testing, the 1.1.0 release is out. This is a new major release following to 1.0.0. This means that you have to do update to your configuration file from v1.0.0 to make it work with v1.1.0. Fortunately there are not many changes to be applied.

Dokuwiki page has been created to track this changes:

Important changes

- AVP parameters of avpops module changed to use same naming schema as pseudo-variables ($avp(type:name))

Packages

What is new?

• enum
1. new functions (or new vresions of them): enum_fquery(), is_from_user_e164(), is_from_user_enum()
   
• group
1. regular expression based group matching added
   
• lcr
1. optional group id parameter is accepted by load_gws(), from_gw(), and to_gw() functions.
2. DB caching support adde.
3. new FROM regexp matching.
4. dynamic strip URI before forward.
• nathelper
1. IPv6 compliant.
2. prope handling of multiple stream handling in sequential requests.
3. support for changing session-level SDP connection (c=) IP when media-description also includes connection information.
4. fix_nated_sdp() may take one more param to force a specific IP instead of the signalling IP.
5. force_rtp_proxy() accepts a new flag 's' to swap creation/confirmation between requests/replies (this is needed to be able to cope with SDPs advertised via 200OK / ACK)
6. add_rcv_param() may take as parameter a flag telling if the parameter should go to the contact URI or contact header; make sense if you forward REGISTER requests and need the registrar to save the parameter as part of URI.
   
   
• pdt
1. multi-domain support added
   
• permissions
1. added "none" protocol option that never matches and thus disables the peer
   
• registrar
1. module may set for TCP connection a custom lifetime for keeping it open as long as the registered contact is valid
2. Path support according to RFC 3327 - support in registrar for loadbalancing using Path-HF with NAT-Support applied
3. request with failed checks are negativly replied with err headers for hints
4. method filtering performed by lookup()
5. 
   
• rr
1. obsolete function strict_route() removed
2. add_rr_param may be called from BRANCH and FAILURE route
3. record_route() may take a parameter containing RR params
4. "lr" param is added as first param to speed up the loose_routing processing
5. record_route / add_rr_param / record_route_preset accept pseudo-variables in params
6. extra checking to void double record routing via record_route and record_route_preset
7. callbacks are executed after all routing changes were done - this allows the usage of callback that may change the routing info without overlappingwith the RR processing.
8. add_username alters also the behaviour of record_route_preset()
   
• sl
1. callbacks added - the only event is sending a stateless reply
2. statistics support added
   
• textops
1. new function has_body([mime])
2. new set of function to work on the body of the message: search_body(), search_append_body(), replace_body(), replace_body_all(), subst_body()
3. function is_method() can be called from BRANCH_ROUTE.
   
• tm
1. fixed branch picking algorithm - if cancelled, but not 487 replied received, fallback and use classical algorithm.
2. fixed in building ACKs for negative replies to local INVITEs. RURI must be the same as in INVITE and Route hdr have no send to be added
3. branch selection algorithm centralized in a single place - more coherent and easier to maintain.
• the selected branch in stored in a static variable to avoid multiple computation for same transaction (so far, each t_check_status() call was triggering computation of the selected branch)
• TM API exports a new function for making public the selected branch (how the winning branch is selected must be transparent for the other modules)
• fixed the branch selection algorithm - if the transaction was cancelled, the "487 Request cancelled" reply will have priority and it will be sent to UAC
4. t_replicate() takes as parameter a SIP URI instead of a destination (in order to align the format as for append_branch()). Also t_replicate() uses the set branches to perform parallel replication to multiple destinations.
5. new TM callbacks added:
   
• TMCB_TRANS_DELETED - called when the transaction is deleted ;
• TMCB_REQUEST_BUILT - called just before sending out a request.
6. "pass_provisional_replies" TM options (pass back through unixsock the provisional replies and not only the final one).
   This was required in order to maintain compatbility with latest SEMS version.
7. module exports $T_branch_idx pseudo-variable refering to the index of the branch for which the branch_route[] is executed
8. advanced TM monitoring
9. t_relay*() returns 1 instead of 0 when forwarding ACK
   
10. relay functions merging:
• t_relay_to_udp(), t_relay_to_tcp(), t_relay_to_tls() merged into t_relay(proto:host:port)
• t_forward_nonack_uri(), t_forward_nonack_udp(), t_forward_nonack_tcp(),
• t_forward_nonack_tls() merged into t_forward_nonack(proto:host:port) and t_forward_nonack()
• t_replicate_udp(), t_replicate_tcp(), t_replicate_tls() merged into t_replicate(sip_uri)
  
• uac
1. default value for "from_restore_mode" switch to auto
2. new module parameter "from_passwd" - used to encrypt the RR parameter which contains the original FROM URI
3. uac_replace_from() adds the display name if not present (so far it only replaced it); uri is enclosed between brackets if not. Actually, now you can set a display name if none was present.
4. when performing UAC authentication, look in predefined AVPs for credentials before using the static set credentials (via modparam)
   

• uri_db
1. "db_url" module parameter may be set to empty string in orer to disable DB support in the module - this is needed if you want to use check_to() or check_from() to check the user against credentials in a non DBenvironment.
• usrloc
1. module is able to detect retransmissions based on Callid and Cseq. The retransmission detecton is controled via the new "cseq_delay" module parameter. REGISTER retransmissions (inside the cseq_delay interval) will not generate error, but they will be accepted and properly replied without any update on the location status. This solves the problem of retransmissions without having a statefullprocessing on requests.
2. advanced monitoring via statistics; module export dynamic statistic for each register domain (as location or aliases). Available statistics: number of registered users (AORs);number of registered contacts (>= AORs); number of expired contacts
   
3. get_contacts fifo and unixsock functions retunrn more additional info related to the contact: expires;flags;socket;methods;received?;user_agent?;path?. Values marked with ? may be missing if empty.
4. usrloc: new DB mode - DB-Only - no memory cache is kept, all operation being directly done into DB. Allows DB sharing between multiple proxies without the need of additional replication mechanism. Drawbacks:
• some performance penalties due intensive DB usage
• location watcher disabled (cannot be bind to a record into mem) => PA cannot be used
• statistics do not work since events cannot be properly been traced without a mem cache
5. contact maching algorithm aligned to the RFC 3261 specs (added extra checking based on callid and cseq)
6. configurable multi-algorithm for contact matching:
• contact only based (as in RFC)
• contac and callid based
7. supported methods are saved into usrloc
8. saved socket info contains now also the protocol. The socket is saved as: proto:ip:port
