Yes we have also seen similar failures for GPRS calls in the osmo-pcu. Our setup uses NuRAN hardware with osmo-bts-sysmo
I can confirm the same behaviour on B200 using master branches of osmo-pcu, osmo-bts-trx, and osmo-trx.
The latest "good" revision I am aware of is commit d87e1d6ab747423d3668c74d16201a5d967accf0 (2015/12/14)
Confirm.
Can somebody confirm or reproduce this attitude ?
The PCU log that we have during failure matches with the one you have reported. We have tried a workaround for this GPRS call failure by forcing two-phase-access in osmo-pcu.cfg. Based on our analysis done till now it seems One phase access of GPRS is broken.
Confirm matching PCU log and that enabling two-phase-access works around the issue.
