Release notes

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-757 FIX: Enabled setting check_fqdn_against_server_cert was not effective for URL's with IP addresses
SAP-782 FIX: Using host_name_validation, (requires check_fqdn_against_server_cert: on, to be effective) IP addresses in TLS server certificates are now handled correctly
SAP-871 FIX: All anonymous authentication ciphers (e.g. ADH-RC4-MD5) removed from Snom TLS stack
SAP-890 FIX: All ciphers removed from Snom TLS stack except TLS_RSA_WITH_AES_128_CBC_SHA

SCPP-7361 FIX: DHCP failover requirement: DHCP client did not fallback to broadcast during renew issues (e.g. DHCP server outages)
SAP-1162 FIX: DHCP option 81 (RFC 4702) was sent erroneously with flag S=0 and it can now be enabled via setting: dhcp_options_on_ip_aquire
SCPP-7931 & SAP-1252 FIX: Improved web client TCP handling of chunked transfer encoding transmissions
SAP-1325 FIX: Web client did not handle a 3xx redirect response when Transfer-Encoding is chunked
SAP-1391 UPD: Changed LLDP manufacturer name from "snom technology AG" to "snom"

SAP-536 FIX: NTP defaults are now queried before secure provisioning, to ensure having valid timestamps for server authentication (if DHCP server does not provide NTP information)
SAP-679 FIX: If provisioning sets tls_server_authentication to on, a reboot is now triggered making it entirely effective and custom root CA certificates can now be provisioned
SAP-767 ADD: A new setting: skip_provisioning_urls_on_tls_error is introduced, but only intented for testing and evaluation purposes
SAP-1076 FIX: By resolving the provisioning server URL the backup DNS server (DHCP provided) was not queried
SAP-1314 FIX: Ensuring backward compatible value handling for setting: web_language

SAP-328 ADD: Milliseconds added to timestamp in log messages, for better analysis
SAP-1262 FIX: Log showed a false positive warning “401 needs 128 bit nonce” (now only for nonces < 128 bits)

SAP-360 FIX: Enabled setting restrict_uri_queries, did block any firmware update attempt via web interface

SCPP-7738 & SAP-1070 UPD: Improved SIP authorization cache handling and introduced a new setting: cache_sip_authorization (default <on>) allows turn off SIP authorization cache
SCPP-6567 FIX: Re-enabled support for incoming SIP TCP connections (see: tcp_listen)
SAP-816 FIX: STUN is now also supported for SIP-TCP / SIP-TLS based registrations
SAP-1106 UPD: Out of order (lower CSeq) responses to an deregistration request will now be ignored (accelerating de- / re-registrations)
SCPP-7823 & SAP-1205 FIX: Device generated an UUID (RFC 4122) on deregistration, when manual setting upload was used exceptionally to take it into operation during an not common migration process
SAP-1280 FIX: Receiving an SIP 380 Alternative Service message raised an unhandled exception
SAP-1429 FIX: A retransmitted 180 was PRACKed (see: RFC 3262 Section 4), - in some cases the cseq was incremented

SAP-564 FIX: With headset / speaker & mic attached to PA1, its line-out & speaker played the mic input during call, - sidetone level was too high
SAP-564 FIX: On LID devices (PA1, 300, 320, 360, 370): No audio during call a after multicast-stream

SAP-439 FIX: Changed default value for setting: advertisement url to https scheme and url to lowercase
SAP-1023 & SAP-733: FIX: In Identity -> NAT (Tab) the setting: initial_rtp_keep_alives is now presented only on models supporting it

Please note: this is a PA1 specific firmware release. Only the PA1 is supported with this firmware:

  • Any PA1 running an firmware >8.7.5.44 should not be downgraded to a version below 8.7.5.44.
  • This may lead to a deadlock situation where the firmware works, but the device cannot be updated anymore at all!
  • All versions lower than 8.7.5.44 are affected by this update procedure issue.
  • Only option left to get out from such deadlock situation is to use the network recovery procedure as described in our support How-to
  • If the downgrade is mandatory, use the 8.7.5.44 as an intermediate firmware downgrade step, before you finally install the desired/known as affected version!
  • Please note: if you experience the deadlock situation do not open an RMA case, as this is not a hardware/flash issue!
