v.1.29.x RtpBridge Releases

V.1.29.0 release 11/11/2014

 [+] Added "uptime" command, which prints RtpBridge's uptime
 [*] Segmentation fault was possible on RtpBridge's exit if remote control interface (i.e. telnet) is actively used during program's exit process   
 [*] Minor fixes in error messages  
 [.] License autosaving into internal memory is back again. It's applied if there is a valid license in a filesystem, but no license is stored in internal memory 
 [.] Improved evaluation mode handling 
 [.] Several optimizations in disconnect handling and data processing   
 [+] Added -report switch to list command ("list -report"), which prints some statistics about active connections (i.e. time passed since last RTP packet arrived)   
 [+] Added /etc/rtpbridge/remote.conf to setup remote control interfaces (Telnet/UDP/HTTP). Currently, it can be used to select, whether control interface's socket should bind to  
      localhost or to all network interfaces (i.e. "telnet bind local")   
 [.] RtpBridge binds UDP sockets, used for "udp" connect points and to send events, to localhost if it's possible (instead of binding to all interfaces)
 [+] RTP's report counting (used in "list -report") is off by default and can be switched on with new command "rtp report on|off"   
 [+] V.110 can be connected to RTP (custom "pseudo" codec is used to carry V.110 payload over RTP)   
 [+] Added new RTP pseudo-codec "custom" (it has alias "v110")

 [+] It is possible to assign RTP payload number to any codec with "rtp map ..." command
 [*] "bert show config" printed incorrect realtime stats printing interval for never started BERT channels
 [.] "helo ..." command is not mandatory for telnet interface
 [+] Added 8 kHz sample-based (8 bits/sample) pseudo-codec "uint8" that can be used for "custom" 64 kbps channels
     with no transcoders or mixers involved in TDM and RTP (i. e. TDM->RTP) area. This pseudo-codec behaves similarly
     with clearmode from RFC 4040 ("clearmode" name is also supported)
 [*] Better file locking on /var/run/... files update (to protect external software from incomplete file reading)
 [*] Does not name RTP payloads, if we have no codecs for them (i.e. G.722)
 [.] Improved mixers in conference (do not treat not connected inputs as silent inputs)
 [+] Very short (shorter than a packet) DTMF events can be detected. The shortest detected event is control with
     "dtmf duration " command, which sets minimum duration
 [*] RTP packets with last portion of DTMF events was not retransmitted (as RFC 4733 states) with E-bit set
 [+] Added Fax<->T.38 (UDPTL) support. See "fax help" command for a list of fax setup commands   
 [.] Faster and safer handling of destruction of some instances that use UDP (udp, tdmop, amr, etc)   
 [+] Fax detection (CNG/CED) on RTP/TDM channels (managed with "fax detect" command)   
  [*] RtpProxy did not set exit flag (used by UDP rx handling thread) on close correctly. It could result in misbehaving thread during RtpBridge's shutdown or on "rtpproxy close" 
      command (if rtpproxy was started with "rtpproxy start")

     and we have no (hw) possibility to have separate clock sources for different spans
 [.] Tiny improvements in /var/run/* files generation
 [*] Generator of /var/run/layer1.json could try to allocate memory for zero spans (if we have no spans)
 [+] It's possible to regenerate /var/run/layer1.json manually with "counters layer1 refresh" command

     data source if necessary. Weak resync jitter timestamp on every jitter buffer depletion.
 [.] Several improvements in board type detection
 [+] Bridge saves license into board internal memory if it is supported, valid license file is provided,
     and there is no license stored in internal memory
 [+] UDP rx connections can be configured to send events on rx timeout
 [*] A-law <-> PCM16 conversions could be incorrect for some values (bug introduced in version 1.16.0)

 [*] Fixed unclear behavior of passthrough bridge when data are ready for the point that does not exist (any more)
 [.] Several changes in "udp" point implementation that allows it to receive bigger datagrams and behave better
     in duplex connections (experimental)
 [.] Tiny improvement in V.32 channel creation command. Option field ('c') is case-insensitive. It is possible to
     specify 'a' ('A') as option for "answer" call
 [.] "Raw AMR" uses packed bit format without reordering

V.1.16.0 Internal release 25/05/2012

 [+] Added echo cancellation support. Commands "ec add/remove/list" manage echo cancellers.

     Commands "rtpproxy start/stop/list" manage RtpProxy.
 [.] Several changes in interfaces to increase data handling accuracy
 [+] Added "codec" connection point that can be used to decode/encode data. This point passes
     encoded/decoded data back to the bridge. So, duplex bridge is required.
 [+] Added V.32 support (experimental). V.32 connection points require duplex bridge
 [+] Added support for duplex connections with "connect duplex" command (experimental)
 [*] Fixed possible issue in UDP ("udp" point) remote address retrieval while receiving data
 [+] Duplex UDP points can get address (if allowed) to send data to by receiving UDP data from that address
 [+] Added "raw AMR" data support. "Raw AMR" is 4.75 kbps AMR frames without any headers (i.e. RFC 4867 headers)
