Fixes:

-=Security=-

REFERENCE-ID TYPE DESCRIPTION
SCPP-6472 UPD: Support only modern Cipher Suites in Server Side TLS. TLS 1.2 ciphersuites reduced from 90 to 42 oriented towards Mozilla Intermediate (Note: more details planned for documentation)
SCPP-6400 UPD: Remove RC4 ciphers from OpenSSL stack (see RFC 7465, note: NULL ciphers are already disabled by default on OpenSSL stack)
SAP-112 FIX: Extended security check on http_proxy and vpn_netcatserver setting. (Not mandatory, if already taken into account: How_do_I_secure_my_phone? )
SAP-158 FIX: Security.htm (http://phone-IP-address/security.htm) web-user-interface page did not show up after settings reset
SCPP-6353 FIX: Unable to logout from the WUI (web-user-interface) in specific case if 'admin_mode_upon_http_login' is enabled

-=Network Protocol=-

REFERENCE-ID TYPE DESCRIPTION
SAP-129 FIX: Align DHCP IPv6 (DHCPv6) handling with default of dhcp_v6 - off --> IPv6 switched off completely
NONE: REV: Re-enable ethernet link detection for snom MP by default
SAP-104 UPD: Default value of ip_frag_enabled should be on --> OOB support for IP fragmentation. Recommended read: IP frag
SCPP-6358 FIX: Snom 710: 802.1x EAP pass-through is not working using VLAN setup via LLDP
SCPP-5810 FIX: Snom 710: 802.1x EAP EAPOL Start packet received on the LAN port should be discarded and not forwarded
SCPP-6343 FIX: Snom 7x5, D7x5 & D3x5: 802.1x EAP pass-through is not working using VLAN setup
NONE FIX: Prevent additional link-down on snom 720 & 760 in advertising gigabit ethernet

-=Provisioning=-

REFERENCE-ID TYPE DESCRIPTION
SCPP-6440
Issue:
Environment:
Solution:
Lost support for path in DHCP option 66, due to aligment with RFC 2132 (DHCP option 66 contains the IP address or the hostname)
All redirection & provisioning solutions, distributing the path and maybe file-name info via DHCP option 66 (e.g. cannot use option 67), (irrelevant of 43 encapsulation is used or not).
Implemented a back- & forward-compatible handling for 66 / 67, covering RFC 2132 and none-RFC 2132 e.g. 66 with path and with/without file name
SCPP-6646
Issue:
Environment:
Solution:
Redirection and/or provisioning are broken as phones stop replacing the {mac} system variable in a given path e.g. http://host.domain.com/{mac}/snom.htm since curly braces are percent-encoded.
All redirection & provisioning solutions using the {mac} variable in paths e.g. provided by DHCP 66/67 (irrelevant of 43 encapsulation is used or not).
Stop percent-encoding for variable / reserved characters, here esp. the curly braces.
SAP-90
Issue:
Environment:
Solution:
XML phonebook feature (e.g. via Action URL) is broken by Percent-encoding of e.g. Semicolon, Equal sign, or other reserved characters, see RFC 3986
Basically all solutions that rely on Action URL's with reserved characters like:  ; or = for example
WebUri path segments will be encoded as specified by RFC 3986
SCPP-6368 FIX: Provisioning of backlight settings (use_backlight, backlight, backlight_idle) are not effective immediately
SCPP-5840 FIX: TR-069: Several Parameters are rejected
SCPP-6288 FIX: TR-069: On new bootstrap without REBOOT TR111 Gateway info lost

-=Firmware Update=-

REFERENCE-ID TYPE DESCRIPTION
SCPP-6662 FIX: Align rescue mode factory reset with factory reset performed by Web-/Phone user interface (ensuring factory-defaults)

-=SIP Signaling=-

REFERENCE-ID TYPE DESCRIPTION
SCPP-6350 FIX: REGISTER request contains the following invalid header: X-Real-IP: {x-snom-adr} , due to missing address substitution
SAP-139
Issue:
Environment:
Solution:
REGISTER requests may fail as they contain the following invalid header: WWW-Contact: <https://%7Bx-snom-adr%7D> due to curly braces being percent-encoded, like in SCPP-6646 (provisioning)
SIP-solutions that expect /require a valid WWW-Contact header
Stop Percent-encoding for this header / reserved characters.
SCPP-6478 FIX: DTMF broken by loss of DTMF RFC2833 negotiation in SDP answer 101 telephone-event, if user_full_sdp_answer is off
SCPP-5989
Issue:
Environment:
Solution:
After holding (or attempt to transfer) a call the phone sends a BYE and shuts down the call, due to SDP answers with amount of m lines not fit the offer (e.g. m=video, or two "m=..." lines in SRTP/SAVP). In case of RTP/SAVP:optional & RTP Encryption:on - the phone immediately closes the call.
SIP-solutions aren't full RFC 3264 compliant, e.g. video-enabled IP-PBX or SRTP / SAVP activated IP-PBX, others
UPD - New setting allow_mismatched_sdp_answers allows SDP answers whose m lines are a subset of the offer (off by default, RFC 3264 compliant OOB, out-of-box).
SCPP-6337 FIX: Transfer / Attended Transfer may fail, as SIP stack does not correctly distinguish URI parameters from header parameters in specific headers (To/From/Contact)
SCPP-6743 FIX: incoming 603 Decline is handled as Busy Here, - no 603 code and / or corresponding message in phone display
SCPP-6578
Issue:
Solution:
Codec G729 (annexb=no) related calls from e.g. a Cisco IP Phone or other equipment (Voip GW, etc.) are aborted by caller, due to missing fmtp SDP line in response
Addding fmtp line to response even if no rtpmap line is present in received SDP
SCPP-6396 FIX: SIP-Subscriptions provisioned / configured via XML Definition get lost
SCPP-6534
Issue:
Environment:
Solution:
Caller ID update (SIP INFO) displays the prefix: sip:
E.g. FreeSWITCH (see: mod_sofia.c#1702)
Implement a back- & forward-compatible handling for invalid To:/From: header used for caller id indication via SIP INFO. No action required if mod_sofia.c#1702 might be updated in the future.
SCPP-6517 FIX: SIP IPv6 grammar must contain the mandated delimiters for IPv6 reference (see RFC 5118 & RFC 3261, the IPv6 reference in the R-URI does not contain the mandated delimiters for an IPv6 reference ("[" and "]")
SCPP-6476 FIX: Safe transfer fails in certain SIP environments, due to Microsoft (Lync/SfB) header ms-sensitivity=private-no-diversion in Refer-To
SCPP-6674
Issue:
Environment:
Solution:
SIP invites via UDP with a certain size can cause hard to manage / handle fragmentation
Networks / solutions using SIP via UDP and facing challenges with fragmentation
Reducing the SIP invite size by removing unused / less common codecs from the default setting (affects new production or F-reset devices - all codecs supported can be re-added, if needed, of course, see Codec and Codec priority, note: page update pending)
SCPP-6377 FIX: If servertype = broadsoft, no headers Required: timer or session refresher are sent, just supported: timers
SAP-113 FIX: ecma TR/87 uaCSTA behaviour of optional 'prompt' and 'doNotPrompt' was always treated as 'doNotPrompt' (zero-interaction on-speaker-call attempt)
SCPP-6383
Issue:
Solution:
Voice quality reports (VQReport) broken, due to wrong format and value of the stop timestamp in the RTCP-XR report, Jitter / Packet loss is always reported as 0
Full refit & maintenance of RTCP, RTCP-XR, RX_Pkts_Lost, Remote_Rx_Pkts_Lost, Timestamps, and BYE values
SCPP-6714 FIX: Voice quality report (VQReport) is missing in SIP PUBLISH

-=Audio=-

REFERENCE-ID TYPE DESCRIPTION
SCPP-5933
& SCPP-6648
Issue: Choppy audio on synthesizer tones, eg. ringing, dial tone, ring back tone, hold (Snom 715/D715,725/D725,D765,D375)
SCPP-6258 FIX: DTMF codes stop working ( no DTMF tone will be heard , nor DTMF codes will be sent in RTP) until a reboot is performed
SCPP-6680
Issue:
Solution:
Static sound during calls in "heavy" Jitter affected scenarios (Snom 720,760 & MP)
Jitter buffer tuning and optimization for Snom 720, 760 & MP
SCPP-6397 FIX: No audio or just noise, as phone changes codec from g729 to g726-32 automatically (no signaling), if g726-32 is set before g729 on codec priority list
SCPP-6522 FIX: Snom 7x5 / D7x5 no audio or one-way audio with G.729 codec
SCPP-6676
Issue:
Environment:
Solution:
SRTP calls only, no audio in a call after approx. 1hr 30min when hold/unhold was pressed
SRTP enforced / optional SRTP solutions
SRTP roll over counter must not set to 0 after hold/unhold
NONE FIX: SRTP calls only - with centralized MoH streaming, Transfers (B xfer's A to C) may result in a one-way audio. A can't hear C.
SCPP-6318 FIX: Snom 720, 760: Incomplete audio after 3-way conference resume
SCPP-6249 FIX: SRTP calls only, Snom MeetingPoint: Distorted audio in a 3-part conference using G.729. MP no longer allows conference with encrypted G.729.
SCPP-6553 FIX: Audio indication for call waiting (CW / CWI) stops frequently (until a reboot is performed)
SCPP-6528 FIX: Turn off cw_dialtone had no effect. On/Off always results in stuttered dialtone followed by a normal dialtone.
SCPP-6524 FIX: Snom 7x5 / D7x5 Bellcore tones fail to properly playout (missing ring splash / short single ring, visual indication only)
SCPP-6674 UPD: remove unused / less common codecs from the default setting (see SCPP-6674 in SIP signaling section, plus Codec and Codec priority, note: page update pending)

-=User Interface=-

REFERENCE-ID TYPE DESCRIPTION
SCPP-6401 FIX: Wrong date is displayed in certain time zones (NZ, US Pacific, Australia, others). UTC offset was not taken into account for affected time zones.
SCPP-6549 UPD: Never show "Provisioning failed" to user via phone user interface (redirection / prov. permanent or temporally out-of-service, or unreachable, users get confronted with warning which they are not responsible for / related to)
SCPP-6171 UPD: Remove Network Wizard (ipv6/vlan/... ) after initial reset of the phone. Besides IPv6 is switched off completely (see SAP-129, Network Protocol), users get confronted with network related settings which they are not responsible for / related to)
SCPP-6523
& SCPP-6349
Issue:
Hint:
Solution:
Multiple cancels required to leave an XML menu, XML menu closes automatically (Transfer / Blind Transfer) or expected result of XML minibrowser query are available but don't show up (looks like missing display refresh)
On http://phone-ip-address/minibrowser.htm?show=STATE you can see the minibrowser-stack growing.
Improve control over Minibrowser-stacking
SCPP-6412 FIX: If DND is activated the DND overlay (symbol & text) is present in call history menu, making it difficult to read.
SCPP-6549 FIX: Disconnected screen is indicated too late, showing wrong disconnected party
SCPP-6416 FIX: Snom 370: Dialing of hash (#) key doesn't work. Results in space instead of hash.
SCPP-6360
& SCPP-6372
Issue: Snom 870: in some menu dialogs incorrectly labeled virtual keys show up, like F_OK and F_CANCEL, F_ABORT
SCPP-6371 FIX: Snom 870: Unexpectedly masked dialed number with an asterisk (*) in call screen
SCPP-6406 FIX: Snom 870: Function keys F3 does not work for XML Minibrowser properly
SCPP-6508 FIX: Photo (caller picture ID ) stored in internal phone book was not displayed on the phone user interface / call screen
SCPP-6417 FIX: The virtual keys screen was auto-closed after around a minute idle time.
SCPP-6294 FIX: Don't offer contrast menu for Snom MeetingPoint.

-=Web User Interface=-

REFERENCE-ID TYPE DESCRIPTION
NONE FIX: Japanese language changes
NONE ADD: Greek phone user interface (PUI) language added
