Description

I am using separate MSC and SGSN for each RAN, osmo-sgsn handles UTRAN->GERAN switching just fine, sending not attached command and causing the phone to reattach.
But when phones move from GERAN to UTRAN only some phones connect to the data network properly, while some are stuck in Activate PDP Context requests
