Release Notes

The list below describes the changes starting from 8.9.3.61

New Features

• SAP-457 ADD: New LDAP picture support on incoming / outgoing calls: Implementation of binary object parameter (as 'jpegPhoto') to display pictures along with LDAP directory entries
• SAP-1040 ADD: Enhanced call forwarding via Pool soft key in all "Target when Forwarding" dialogs. All Pool contacts (LDAP, Call History, Directory, etc.) can now be set as target for CFWD operations
• SAP-496 ADD: New setting to display or suppress messages received via SIP MESSAGES outside an INVITE shown in call screens, - see show_desktop_msg_in_call_screens for more details
• SAP-567 ADD: New setting xfer_dest_order_lifo allows to customize in which order held calls are presented during an attended transfer scenario (last in first out)
• SAP-1551 ADD: Enhanced call_join_xfer with new value "always" enables invoking immediate transfer via transfer key, without additional selection and confirmation, independant of how many calls are on hold
• SAP-1578 & SCPP-205 ADD: Transfer with Line keys is now supported, - also works for BLF, Extension, speed dial, presence. E.g. in attendant transfer select transfer destination via corresponding flashing Line key.
• SAP-1588 ADD: New setting to disable / enable "blacklisting callers via long press cancel key on incoming", - don't miss to see long_cancel_is_blocking_caller for more details
• SAP-1497 ADD: New remote / server based blacklisting, via introduction of a new action URL action_blacklist_url and related remote_blacklist_action_timer. Please note: this is entirely decoupled from phone internal Contact Type "deny list" and aforementioned SAP-1588
• SAP-1706 ADD: New Long Press / LP-feature introduces Phone User Interface and provisioning configuration of long press event support for every Line Key: fkey_longpress is on per default
• LP-feature allows e.g. the reconfiguration of the Line Key that was long pressed or supports remote XML application calls when combined with Action URL for long press. Please note: for several key types contradictory to long press event support like e.g. P2T - Push2Talk the LP-feature needs to be turned off. Also applies when using XML defined keys with on press / on release attributes
• SAP-1871 FIX: Enhanced key event F_REDIAL, which opens the dialed section in call history now also acts as OK allowing to call the selected number using same Fkey.
• SAP-1574 ADD: New interupt parameter value: 2 for mc_address allows mixing scenarios with normal calls & multicast, including call audio split for remote party (supported on D7xx & D3x5). Please note: to ensure a multicast can also interrupt during hold, cw_dialtone needs to be set to: off
• SAP-1323 ADD: New immediate SIP failover when ICMP is received. SIP stack now acts on ICMP messages, - before failover could be inordinately long due to timeouts of requests send to invalid address
• SAP-1410 ADD: New multiple value (SIP response codes & reason phrases) support for sip_failover_response_reg & sip_failover_response
• SAP-1341 ADD: New support for primary & secondary (multiple) provisioning server for redundancy via FQDN (DNS query returns multiple IP addresses). Please take swupd_curl_timeouts also into consideration regarding firmware update scenarios that include provisioning redundancy
• SAP-1496 ADD: New support for Periodic Provisioning Server Polling, - see /advanced_update.htm in device Web User Interface for new setting like prov_polling_enabled

Security

• SAP-1836 FIX: WPA2 patched against KRACK WPA 2 exploit
• SAP-1653 FIX: MD5 value set on user_hash is now treated as secret as user_pass. Please note: general Web User Interface protection improvement is strongly recommended e.g. in strict accordance with FAQ:How_do_I_secure_my_phone
• SAP-1346 FIX: TR-069 port (7547) is now closed if TR-069 is not used
• SAP-568 FIX: The lock symbol in display indicating an SIPS/SRTP secured call remained after call was ended, or when SRTP switched to RTP during a call, e.g. in receiving not encrypted MoH
• SAP-1897 FIX: Default value for host_name_validation_flags changed from 2 to 0 to re-enable support for wildcard SSL certificates, - review host_name_validation_flags for more details & effectiveness
• SAP-1933 FIX: Removed an expired preinstalled certificate (CN=DST ACES CA X6,OU=DST ACES,O=Digital Signature Trust,C=US) and added: IdenTrust Public Sector Root CA 

Network Protocol

• SAP-1325 FIX: Web client did not handle a 3xx redirect response when Transfer-Encoding is chunked
• SAP-1736 FIX: An LLDP-MED packet with policy: VLAN: 0, DSCP: 0, VLAN Prio: 0 was processed as a new policy initiated a reboot, ultimately led to a reboot-loop, - also perceived as a crash due to the deferred reboot execution. Please note: issue was introduced in 8.9.3.60 May 2017 via SAP-611, - corrections included in SAP-611 remain intact
• SAP-1378 FIX: Snom D712: POE class in LLDP was adjusted for D712, - it sends now "Power Value: 3800 mW" via LLDP
• SAP-1391 UPD: Changed LLDP manufacturer name from "snom technology AG" to "snom"

Diagnostics

• SAP-1676 ADD: Phone reports UXM (D3 / D7) version info & UXM count when available, via Phone User Interface: System info and via Web User Interface: /info.htm and /support.htm

Firmware Update

SIP Signalling

• SAP-1416 FIX: Receiving Expire = 0 on Register did not trigger custom retry interval (see: retry_after_failed_register), - timer for failed registration was ignored and register send after default: 300s
• SAP-1429 FIX: A retransmitted 180 was PRACKed (see: RFC 3262 Section 4), - in some cases the cseq was incremented
• SAP-1572 FIX: Snom D3x5, D7x5 & D712: If the SSRC is changed during shift from early media to the proper rtp without a new call setup, an rtp delay with up to ~3 seconds of no-audio could be observed
• SAP-1632 FIX: If an previously negotiated session intervall was during an HOLD refused with "422 Session interval too small", the new proposed was ignored for RE-INVITE, - resulting in a local HOLD
• SAP-1821 FIX: If an SDP is received in an 181 "Call is Being Forwarded" it was not processed, no early media was played at the 181, ultimately led to call was dropped / ended with BYE directly after 200 OK
• SAP-1848 FIX: Receiving multiple m-lines in an SDP, a parsing error led to apply the second m-line even it was disabled and had a status sendonly (in the specific case), - ultimately caused one way audio scenarios
• SAP-1215 FIX: BLF's configured with XML definitions could loose the subscription

• SAP-609 FIX: Snom 710 / D710: Loss of DTMF or Call Waiting tone after ~280 calls received
• SAP-1573 FIX: Snom 710 / D710: DTMF (in-band) stopped working after ~400 calls and needs a reboot to recover it

User Interface

• Generally: Extensions and corrections of icons, particularly for monochrome high resolution models plus aligning the low resolution models to it. Minor text adjustments, centering, upper & lower case corrections, etc. Minor improvements in Web User Interface and Phone User Interface. Always scroll title, messages etc. if texts are too long. Improved image cache robustness. Several text cut-offs addressed
• SAP-1518 FIX: Snom 760 (solely HW Revision R1A): Scrolling with navigation key did not work properly within e.g. Directory and Timezone, was skipping entries or a whole page. Please note: was caused by an regression introduced with the release 8.9.3.60 from May 2017 - No need for an RMA!
• SAP-1729 FIX: D305 & D315: if mute_is_dnd_in_idle is ON, the Mute key led does now lit-up / goes off aligned with DND is active / inactive

• SAP-779 FIX: Now all phones indicate that VPN is in use in display (limited to 8.9.3.x supported models)
• SAP-1375 FIX: With CFWD enabled on color screen phones the call forward overlay was blocking the user from reading the call history
• SAP-1405 FIX: Only on color display phones in multicast scenarios: Speaker symbol was displayed too late when changing from headset to speaker
• SAP-910 FIX: The backlight remained constantly on, even no minibrowser instance was active - like minibrowser exit was not entirely completed
• Please note: this was also indicated via debug pages /state_of_gui.htm: "BACKLIGHT constant_on" and /minibrowser.htm: "No active minibrowser instance"

LDAP

• SAP-653 FIX: ldap_predict_text=on combined with guess_number=on can lead to unlimited length of query string

Other

• SAP-1339 FIX: Large local directory (e.g. 2000 entries) slowed down the phone significantly on incoming call, as the search takes very long
• SAP-1546 FIX: If user_pic is set to an URL that is invalid or unresolvable the phone significantly slows down esp. during repetition of fetch attempts
• SAP-1738 FIX: If an unsupported image size (dimensions) was provided to the phone via custom_bg_image_url the phones crashed and ultimately led to a crash-loop as long the image was downloaded yet again
• SAP-1800 FIX: In particular case, where the phone is transferred to a target that forwards the call to a target that rejects the call, the phone crashed frequently
• SAP-1415 FIX: The support for XmlSubTags/action on press / on release was recovered. Please note: the new LP-feature introduced with SAP-1706 (listed above under new features) needs to be turned off for the respective key via fkey_longpress
