- Parameter "morsegerman" for option "local-tones" will generate morse-a dialtone (pre-1979).
- Fixed german tone pattern timings according to 1TR110-1 Chapter 8
* Busy tone: 480ms on / 480ms off
* Hangup tone: 480ms on / 480ms off
* Old german ringing: 1000ms on / 4000ms off
* Old german busy/hangup tone: 125ms on / 475ms off
- 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
- Attach AOC-E to DISCONNECT or RELEASE; transmit AOC-E even if zero units have been charged
- Send AOC-D with zero units to indicate free of charge call
- New option "time-no-seconds" disables sending current seconds within the date/time IE
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.

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.
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
When (exclusive or suggested) channel is offered, we must "seize" it, so that
it is linked with call instance. Still the channel might be changed on reply.
