2023-03-26libosmo-cc: Fix critical bug in RTCP handlingAndreas Eversberg1-1/+1
Upon an RTCP read event, read from RTCP socket and not from RTP socket.

2023-01-21Make libtimer to be osmo_* compatible in some placesAndreas Eversberg25-90/+141
2022-12-16libosmo-cc: Fixed NULL-pointer bugAndreas Eversberg1-0/+2
2022-12-16FSK modulator improvementsAndreas Eversberg6-50/+137
1. Phase is now changed proportional to the time of the bit change, if it happens somewhere between samples. The amount of phase change per bit is now the same for all bits, no matter how many samples currently lay inside this bit. 2. IIR filter is removed, because it causes distortions. A cosine shape is now used to transit between phase change of F0 to F1 and vice versa. This limits the spectrum. This filter is optional.
2022-12-16Resampling filter can now be turned offAndreas Eversberg2-4/+10
Only linear filtering remains when off.
2022-12-16Removed obsolete hexdump function from DTMF decoderAndreas Eversberg1-17/+2
2022-12-16Fixed a bug on datenklo's ioctrlsAndreas Eversberg1-1/+1
2022-12-16Osmo-CC: Change UPDATE to MODIFY messageAndreas Eversberg2-6/+24
Naming it UPDATE was not a good idea. Now this is renamed to MODIFY message, related to MNCC (GSM). It is used to change media coding during a call. It allows new codec negotiation using SDP protocol and/or changing RTP peer. Also useful for SIP.
2022-11-24osmo-cc: Add private pointer to codecsAndreas Eversberg9-58/+58
2022-11-24osmo-cc: Set session to NULL, if no codec matchesAndreas Eversberg1-0/+2
Applications will crash, due to use-after-free bug, if this is not done.

2022-10-23Osmo-CC: Add marker bit supportAndreas Eversberg8-22/+22
2022-10-23Osmo-CC: Add UPDATE messagesAndreas Eversberg2-0/+18
2022-10-23DTMF: Now allows to give duration and pause for digitAndreas Eversberg9-44/+74
Also the dtmf encoder will return less samples, if the digit(+pause) ends, so that the caller call set the next digit to play seamlessly. A reset function allows to clear the decoder states, to prevent glitches when re-attaching to an interrupted stream.
2022-10-23libsample: Add another function for converting between int16_t and sample_tAndreas Eversberg6-10/+37
Now we have speech level and 1mW (0 dBm) conversion functions

Tested with MT209 phone.
2022-10-23Refactoring jitter bufferAndreas Eversberg42-209/+547
Features are: * Packet based buffer * Random in, first out * Adaptive delay compensation (voice) * Fixed delay (data, optionally MODEM/FAX) * Interpolation of missing frames * Any sample size

2022-07-23C-Netz: Changed voice diversion back to 2.4 KHzAndreas Eversberg1-3/+3
Most phones use this deviation. C5 does not for some unknown reason.
