Usable both as a fallback for the PBX as well as - The Autoattendant functionality that was previously only available on Convergence GW devices has now been merged. This enables you to use the Convergence for making Announcements or IVR menus. This can be done either directly from the gateway to the Convergence to have the Convergence act as a virtual gateway for the PBX, or through the PBX. The Convergence acts as a SIP Subscriber in those cases. The features include Announcements, Prompts and Menus with DTMF Input - Conferencing functionality was integrated (formerly only available in Convergence GW). This means that the device can now act as a MeetMe Conferencing Server with Meeting Rooms, Moderators, as well as PIN request for entering a conference - Voice Recording functionality. This enables you to define a policy for recording calls. The recorded calls can be downloaded from the WebGUI. There is also a user GUI enabling the download of this information - Unit Manager Network Central Management Tool Support - It is possible now to do a "Factory Reset" from LCD display for all units that support this - SBC template now available on the Convergence 1600 - Support Info File that enables you to collect Debug information with a single Click containing all required information for Support to identify the problem - WebGUI Improvements that include in page dialogs, better error information, help information, as well as numerous other new features - Configuration Rollback functionality that allows you to go back to an arbitrary previous configuration - Remote Backup functionality for the configuration to save the configuration to an external system - SBC functionality now fully dynamic on all interfaces. No IP specification necessary anymore - SBC now fully supports Topology hiding both for all informative headers as well as for the routing headers such as Record-Route, VIA, Route ----------------------------------------------------------------------------------- Bug Fixes: ----------------------------------------------------------------------------------- - Changed timescale for TCP connect timeout from seconds to tenths of a second (default now 0.5s). This fixes a problem that if e.g. a TLS phone is unplugged and is not reachable anymore this messaging thread was blocked for several seconds. If that happened with 4 messages at the same time, all message handling threads were blocked - Do not delete /etc/sysconfig/network-scripts/.post or /etc/sysconfig/network-scripts/ifcfg-* containing the magic text DO_NOT_DELETE during update and applyconfig - Added support for second PBX node also in Branch SBC mode (ported from Survuvability) - The B2BUA now accepts SIP messages with with mixed/multipart bodies as for example used by Nortel PBXs. - Route Headers correctly removed if Topology Hiding is activated in SBC mode - The Transport Parameter is now correctly added in Record Route Headers even if Preset Record Route or VRRP virtual addresses are being used - It is now possible to correctly dial a number starting with a * in Survivability mode with B2BUA enabled. - Space optimizations were made to clear some unnecessary stuff from the flash - The B2BUA in Survivability mode now plays a correct ringback tone between initiating a Transfer and getting an Answer - No DNS Reverse Lookup queries are exectued in Survivability mode - The Cache timeout for the Survivability cache is now correctly calculated based so that the constant ping will always occur every 60 seconds and not vary based on the set timeout. - In the visualization of the SIP Proxy Registered Users, the windows is unnecessarily small - Max-Forwards header missing in ACK has been fixed - TLS - sporad. no SIP-Options to PBX sent out anymore after proxy-restart. This was a timing issue during the startup that has been resolved. - Increased timeout for SIP messages handled by the SIP proxy to 200 seconds. This means that the SIP Proxy will only respond with 480 after 200 seconds and not receiving any other response to that transaction. - SIP Proxy users now again properly displayed in the WebGUI - Improvements to the WebGUI for giving proper warnings both in the SNMP page and the QoS pages - Corrected Subscribe handling in conjunction with PBX Alias Setting in Branch SBC and Survivability templates - SIP Proxy Status (Survivability or normal mode) is now properly displayed in the WebGUI again - Fixed missing Max Forwards header for ACKs sent by the Server (IP PBX) - Fixed bug in the SBC that led to improper handling of OKs with two SDP streams if the initial INVITE had no SDP at all - DHCP problem in conjunction with SIP Proxy. It is now possible for the product to get an IP address from a DHCP Server when using the SIP Proxy - Fix syntax errors in survivability and branch scripts for generating CDRs in Surv. mode (bug introduced only in .24 version) - Set correct interface names in bandwitdh operation instead of Lan1, Lan2 or Wan (bug introduced only in .24 version) - Fixed syntax error in Dual Registration (bug introduced only in .24 version) - Fix SIP proxy restart. Now all old registration from the dump file are restored correctly - Fixed error in Survivability in conjunction with the Map Prefix feature that garbled the numbers - Fixed problem when directly upgrading from 3905 that Configuration file for SIP Proxy is missing because it is not properly converterd. Manual CLI intervention was necessary before - After an upgrade the SIP proxy needed to be started manually because the TLS certs were not automatically generated - B2BUA now supports correctly down negotiating from SRTP to RTP - Fixed wrong record routing in conjunction with TLS and VRRP as well as the Preset Record Route Feature. In those cases the transport parameter was missing. - External Prefix Parameter was not applied correct if it contained special characters (e.g. *,#) - Fixed Record Route setting for TLS in conjunction with B2BUA mode in limited Mode - Fixed configuration generation errors in CAC handling in survivability mode - B2BUA now plays music between transfer and answer (now also works for updates and not only newly delivered boxes) - B2BUA now accepts SIPS URIs - Fixed some issues in VIA Header Hiding for SBC - Fixed several message routing issues in conjunction with survivability and B2BUA that caused messages to be sent over UDP instead of TLS - Fixes have been made to the message routing as well as the record routing in conjunction with mixed protocol operation especially if PBX speaks different protocol than the connected phones, or the phones speak different protocols - Comdasys, B2BUA in limited Mode wrong record route setting was solved - Refer instead of Forbidden is sent to gateway via Comdasys was fixed. If a phone rejected a Transfer request, the unsuccessful response was not forwarded to the gateway. Instead hunting was attempted which was of course a bug. - Fixed a memory leak in record route handling that lead to a service crash about once a week under high loads - Fixes to Apply Configuration for groups in the WebGUI - Fixes for SURVIVABILITY NOTIFY sending to avoid phones being stuck in Surv. mode - Fixed another memory leak when relaying messages to locally connected phones (this leak was only introduced in the .27 so earlier versions did not have this problem) - Console handling (trailing cursor) on Convergence 650 has been fixed - Autoattendant Outboundproxy functionality fix - L2TP / IPSEC fixed for Windows Vista - SIP Options for Surviavbility ping now RFC compliant Contact header even if SIP From host set - SBC components restart now possible online ----------------------------------------------------------------------------------- Changes and Bugfixes (vs 6719.3 Releases): ----------------------------------------------------------------------------------- - Fixed instabilities in conjunction with TLS and also in generic scenarios that caused occasional crashes.

This parameter has not been configurable since 4675.9 and now must be removed for ensuring proper behavior. - Fixed problem in media handling that led to a signal handling process stop doing media handling after encountering one unhandled error. Now the signal handling process properly recovers and functions normal again. Only relevant for Branch SBC and SBC templates - Fixed problem with SIP devices that do not properly advertise port and transport in their contact header (only encountered with old V5 firmware of Mediatrix 1102 so far) - The User Configuration is removed from the Admin WebGUI - The Voice Recording Admin can of course also change his password. After the first activation of this Feature by the WebGUI Admin, the Voice Recording Admin can log in with a default password. - Voice Recording policy configuration is moved to the Voice Recording GUI . - Voice Recording GUI now via HTTOS - CLI password and Admin password can now be separated - File naming of recorded conversations changed - Voice Recording now records pcap files for analysis with Wireshark ----------------------------------------------------------------------------------- Changes and Bugfixes (vs 6719.5 Releases): ----------------------------------------------------------------------------------- - Fixed problem with SIP devices that do not properly advertise port and transport in their contact header (only encountered with old V5 firmware of Mediatrix 1102 so far) - Fixed a SIP routing issue: Attanded transfer in survivability mode from TLS phones to UDP was not working - Improved TCP/TLS logging messages - Improved reliability in SIP proxy.
