RFC4040 experiments

manawyrm is playing with getting a Yate PBX to signal SIP CLEARMODE ISDN traffic over to a DAHDI ISDN line...


Data calls (file transfers, G4 Fax, etc.) work perfectly.
H.320 video telephony doesn't negotiate properly?

The origin of the "Buffer overruns" is currently unknown, it also occurs with regular alaw voice calls, so this is unrelated to these experiments.
Further investigation needed.
