New option "time-no-seconds" disables sending current seconds within the date/time IE.
Some phones ignore the date/time IE if it is more precise than the current minute.
- Fix: AOC-D unit information length was set to 1 despite its actual length
- Removed optional BillingID from AOC-E data
- Cross-checked AOC-D and AOC-E IEs to other systems (Audiocodes Mediant 800; traces found in public sources)
- Tested with ISDN TEs: Siemens Profiset 51, T-Concept P522, Philips SOPHO ErgoLine, sphairon NT1PLUS-split; K1297 ISDN protocol tester
The durationCurrency typeOfCharging=stepFunction is more suitable to a per-unit metering than continuousCharging. stepFunction implies start of the first unit at call connect - for normal calls without additional unit charges for call setup, chargedItem CallSetup is set to FreeOfCharge.
Source: ETS 300 178
Tested with Bluephone and Clubtelefon 5 ISDN.
encodeAOCDChargingUnitOperation() set the value of TypeOfChargingInfo to Total, which results in ISDN phones not correctly displaying increasing units. Setting it to SubTotal fixed the issue.
If metering details via IE_METERING are received from osmo-cc, AOC-S and/or AOC-D facility IEs are attached to PROCEEDING/ALERTING/CONNECT messages, and AOC-D facility messages are generated during the call. This feature can be enabled by setting 'aocs' and/or 'aocd' within the mISDN endpoint configuration.
- Some ISDN terminals require AOC-E information to increment their internal unit counter. Tested with Siemens Profiset 51
- Fixed encodeAOCEChargingUnitOperation() producing incorrect AOC-E IE. Tested with K1297 protocol analyser, protocol ETSI-SupplementalServices

Channel selection in that mode must be forced, so that the TE nay not
select a different channel. In that mode the TE cannot know what
channel is allocated, so it cannot select a different channel.
Eumex PBX rejects calls without this fix.
* Use raw bchannel instead of DSP feature
* Removed DSP features
* Use new jitter buffer and control TX FIFO load by this application
* Added bridging daemon to assign time slots for bridging
